waves into free-space modes, opening the road to truly two-dimensional

[pdf/
arXiv/

Abstract:
We resolve the long-standing controversy regarding far-field imaging by a
planar lens made of a left-handed medium and demonstrate theoretically that the
far-field image has a fundamentally different origin depending on the
relationship between losses inside the lens and the wavelength of the light,
l. At small enough l, the image is always
governed by diffraction theory, and the resolution is independent of the
absorption if both Im[e]<<1 and Im[m]<<1.
For any finite l, however, a critical absorption
exists below which the superresolution regime occurs, although this absorption
is extremely low and can hardly be achieved. We demonstrate that the transition
between the diffraction-limited and superresolution regimes is governed by a
universal parameter combining absorption, wavelength, and lens thickness.
Finally, we show that this parameter is related to the resonant excitation of
surface plasma waves.

Abstract:
We derive an approach to define the causal direction of the wavevector of modes
in optical metamaterials, which in turn, determines signs of refractive index

permittivity and magnetic permeability. We use the developed technique to
demonstrate that the interplay between resonant response of constituents of
metamaterials can be used to achieve efficient dispersion management. Finally
we demonstrate broadband dispersion-less index and impedance matching in active
nanowire-based negative index materials. Our work opens new practical
applications of negative index composites for broadband lensing, imaging, and
pulse-routing

semiconductor metamaterials" - Nature Materials 6, 946 (2007)
[url/
first paragraph]
Abstract:
An optical metamaterial is a composite in which subwavelength features, rather
than the constituent materials, control the macroscopic electromagnetic
properties of the material. Recently, properly designed metamaterials have
garnered much interest because of their unusual interaction with
electromagnetic waves1-3. Whereas nature seems to have limits on the type of
materials that exist, newly invented metamaterials are not bound by such
constraints. These newly accessible electromagnetic properties make these
materials an excellent platform for demonstrating unusual optical phenomena and
unique applications such as subwavelength imaging and planar lens design.
'Negative-index materials', as first proposed, required the permittivity, ",
and permeability, μ, to be simultaneously less than zero, but such
materials face limitations. Here, we demonstrate a comparatively lowloss,
three-dimensional, all-semiconductor metamaterial that exhibits negative
refraction for all incidence angles in the long-wave infrared region and
requires only an anisotropic dielectric function with a single resonance. Using
reflection and transmission measurements and a comprehensive model of the
material, we demonstrate that our material exhibits negative refraction. This
is furthermore confirmed through a straightforward beam optics experiment. This
work will influence future metamaterial designs and their incorporation into
optical semiconductor devices.

Abstract:
Classical counterparts of a great variety of quantum systems, from atomic
physics to quantum wells and quantum dots, to optical, microwave, and acoustic
resonators exhibit partially chaotic dynamics. Since it is often impossible to
measure the temporal dynamics in qunatum systems, the main and probably the
most dramatic manifestation of classical chaos in their phase space is seen in
the distribution of spacing between the neighboring energy levels. While the
mechanism leading to the onset of chaotic dynamics is different in every
system, the level spacing distribution obeys the universal law, changing from
Poissonian in the completely integrable systems to Wigner in completely chaotic
ones

Abstract:
We study the energy propagation in subwavelength waveguides and demonstrate
that the mechanism of material gain, previously suggested for loss
compensation, is also a powerful tool to manipulate dispersion and propagation
characteristics of electromagnetic pulses at the nanoscale. We show
theoretically that the group velocity in lossy nano-waveguides can be
controlled from slow to superluminal values by the material gain and waveguide
geometry and develop an analytical description of the relevant physics. We
utilize the developed formalism to show that gain-assisted dispersion
management can be used to control the transition between ``photonic-funnel''
and ``photonic-compressor'' regimes in tapered nano-waveguides. The phenomenon
of strong modulation of group velocity in subwavelength structures can be
realized in waveguides with different geometries, and is present for both
volume and surface-modes.

Abstract:
We present waveguides with photonic crystal cores, supporting energy
propagation in subwavelength regions with a mode structure identical to that in

frequencies, and demonstrate ~10...30% energy transfer to and from regions
smaller than 1/25-th of the wavelength via numerical solution of Maxwell
equations. Both positive- and negative-refractive index light transmissions are
shown. Our approach, although demonstrated here in circular waveguides for some
specific frequencies, is easily scalable from optical to IR to THz frequency
ranges, and can be realized in a variety of waveguide geometries. Our design
may be used for ultra high-density energy focusing, nm-resolution sensing,
near-field microscopy, and high-speed photonic computing.

We develop an approach to use nanostructured plasmonic materials as a

design does not require periodicity and thus is highly tolerant to fabrication
defects. Moreover, since the proposed materials are intrinsically non-magnetic,
their performance is not limited to proximity of a resonance so that the
resulting structure has relatively low loss. We develop the analytical
description of the relevant electromagnetic phenomena and justify our analytic
results via numerical solutions of Maxwell equations.

Abstract:
We report the demonstration of surface-plasmon microcylinder quantum cascade

fabrication technique was developed that allows the use of wet etching,
necessary to achieve smooth and clean surfaces, in combination with the
deposition of the surface-plasmon-carrying metal layer up to the very edge of
the resonator, where the optical mode is mostly located. The diameter of the
microcylinders ranges from 75 to 180 /spl mu/m while their deformation
coefficient /spl epsiv/ ranges from /spl epsiv/=0 to /spl epsiv/=0.32. Circular
microcylinder lasers show a reduction of /spl sim/50% of the threshold current
density with respect to devices with standard ridge-waveguide resonators. On
the other hand, highly deformed microcylinder lasers exhibit a complex mode
structure, suggesting the onset of chaotic behavior.

Abstract:
We analyze the performance of a planar lens based on realistic negative index

expression for the resolution limit of a generalized lens, use it to find the
optimum lens configuration, and calculate the maximum absorption practical
nearfield superlenses may have. We demonstrate that in contrast to the
conventional superlens picture, planar imaging is typically accompanied by
excitation of surface waves at both interfaces of the lens.

p.3999 (2005)
[ url/
abstract
]
Abstract:
Enlarging upon work of Nicorovici, McPhedran, and Milton (1994) a rigorous
proof is given that in the quasistatic regime a cylindrical superlens can
successfully image a dipolar line source in the limit as the loss in the lens
tends to zero. In this limit it is proved that the field blows up to infinity
in two sometimes overlap- ping annular anomalously locally resonant regions,
one of which extends inside the lens and the other of which extends outside the
lens. If the object being imaged responds to an applied field it is argued that
it must lie outside the resonant re- gions to be successfully imaged. If the
image is being probed it is argued that the resonant regions created by the
probe should not interfere with either the probe itself or the object being
imaged, if that object responds to an applied field. Per- fect imaging in a
cylindrical superlens is shown to extend to the static equations of
magnetoelectricity or thermoelectricity provided they have a special structure
which makes these equations equivalent to the quasistatic equations.

Abstract:
We demonstrate the lasing action from a dynamically localized mode in a
microdisk resonator with rough boundary. Although substantial boundary
roughness and surface defects in our devices imply strong light scattering and
destroy the regular whispering gallery modes, the destructive interference of
the scattered light leads to the dynamical Anderson localization in the phase
space of the system and the formation of a different type of high-Q modes.
Using direct optical imaging of the lasing mode and theoretical calculations,
we show that the lasing modes in our devices has dynamical localization origin.
This behavior, although demonstrated here in GaAs-InAs microdisk laser, should
be applicable to any lasers and sensors based on semiconductor or polymer
materials

surface (polariton) waves, and show the connection between the polaritons and
the enhancement of evanescent fields, also known as superlensing.

Abstract:
The materials with simultaneously negative dielectric permittivity and magnetic
permeability also known as left-handed materials (LHMs), are among the most
rapid-developing topics in the modern scientific community due to their
exciting and often unnatural electromagnetic properties. The ``ultimate
application'' of LHM is the construction of a lens with ``perfect''
(subwavelength) optical resolution in the far field, which -- although
potentially leading to a tremendous advance in imaging, fabrication, and
communications -- have initiated a lot of controversy. In the present work we
show that the LHM-based lens ceases to be perfect in the presence of even a
small absorption and the area of its subwavelength resolution is usually
limited to the proximity of the scatterer, similarly to well-developed
near-field optics. We derive the relation between the focal distance and
resolution of the superlens, and resolve the above mentioned controversy

Abstract:
Hashiguchi has studied the limitedness problem of distance automata (DA) in a
series of paper [(J. Comput. System Sci. 24 (1982) 233; Theoret. Comput. Sci.
72 (1990) 27; Theoret. Comput. Sci. 233 (2000) 19)]. The distance of a DA can
be limited or unbounded. Given that the distance of a DA is limited, Hashiguchi
has proved in Hashiguchi (2000) that the distance of the automaton is bounded
by 24n3+n lg(n+2)+n, where n is the number of states. In
this paper, we study again Hashiguchi's solution to the limitedness problem. We
have made a number of simpli=cation and improvement on Hashiguchi's method. We

tunneling" - Phys.Rev.Lett. 91, 263601 (2003)

Abstract:
We study tunneling between regular and chaotic regions in the phase space of
Hamiltonian systems. We analytically calculate the transition rate and show
that its variation depends only on corresponding phase space area and in this
sense is universal.We derive the distribution of level splittings associated
with the pairs of quasidegenerate regular eigenstates which in the general case
is different from a Cauchy distribution. We show that chaos-assisted tunneling
leads to level repulsion between regular eigenstates, solving the longstanding
problem of level-spacing distribution in mixed systems.

refraction in metal nanowire composites" - Optics Express 11 735

Abstract:
Optical properties of metal nanowires and nanowire composite materials are
studied. An incident electromagnetic wave can effectively couple to the
propagating surface plasmon polariton (SPP) modes in metal nanowires resulting
in very large local fields. The excited SPP modes depend on the structure of
nanowires and their orientation with respect to incident radiation. A nanowire
percolation composite is shown to have a broadband spectrum of localized
plasmon modes. We also show that a composite of nanowires arranged into
parallel pairs can act as a left-handed material with the effective magnetic
permeability and dielectric permittivity both negative in the visible and
near-infrared spectral ranges.

Abstract:
The electromagnetic field distribution for thin metal nanowires is found, by
using the discrete dipole approximation. The plasmon polariton modes in wires
are numerically simulated. These modes are found to be dependent on the
incident light wavelength and direction of propagation. The existence of
localized plasmon modes and strong local field enhancement in percolation
nanowire composites is demonstrated. Novel left-handed materials in the
near-infrared and visible are proposed based on nanowire composites.

Optical Responses and sub-fs Pulse Generation in Semicontinious Metal Films"

[ pdf/

Abstract:
In metal-dielectric percolation films, plasmon modes are localized in nm-sized
areas, "hot-spots," where EM-field is extremely enhanced. When the excitation
pulse has a broad spectrum, sub-femtosecond opti- cal responses can occur
locally on such films. Thus, sub-wavelength spatial localization and
sub-light-period time localization are both possible in metal-dilectric
percolation films.

Transmittance through Metal Film with Subwavelength Holes" IEEE J. of
Quantum Electronics 38, 956-963 (2002).
[ pdf /
abstract ]
Abstract:
An analytical theory for extraordinary light trans-mittance through an
optically thick metal film with subwavelength holes is developed. It is shown
that the film transmittance has sharp peaks that are due to the Maxwell-Garnet
resonances in the holes. There are localized electric and magnetic resonances
resulting in, respectively, dramatically enhanced electric and magnetic fields
in the holes. A simple analytical expression for the resonance trans-mittance
is derived that holds for arbitrary hole distribution. It is also shown that
there are other types of transmittance resonances, when the holes are arranged
into a regular lattice. These reso-nances occur because of the excitation of
surface plasmon polari-tons propagating over the film surface. A combination of
the two kinds of resonances results in a rich spectral behavior in the
extra-ordinary optical transmittance.

multiphoton-excited light emission from Ag aggregate-adsorbate complexes in
microcavity", J. of Modern Optics 49, 645 (2002).
[ pdf /
abstract ]
Abstract:
A novel class of composites for optics, microcavities doped with metal fractal
aggregates, is studied. Lasing and broad-band Stokes and anti-Stokes emission
from (Ag colloidal aggregates)/(adsorbed molecules)/(micro-cavity) composite at
low-intensity cw and pulse laser excitation has been found. At 633 nm cw
excitation wavelength the emission spectrum contains many peaks, spanning a
range from wavelength 200 nm to 800 nm. Experiments with pulse excitation of
Ag/dye/microcavity composite show that the duration of the observed broad-band
anti-Stokes emission significantly exceeds the pump pulse duration, dye
molecule fluorescence time, and relaxation times in silver particles. It may be
interpreted as a luminescence governed by long-living triplet states of dye
molecules. These observations were made possible by use of a
fractal-microcavity composite, where coupling the localized plasmon modes in
fractal aggregates with microcavity resonances is provided. The important role
of multiphoton resonant transitions between discrete states of a finite-size
metal particle in enhanced local fields is shown. Analysis, based on the model
of a spherical potential well, shows that the observed spectra contain
fingerprints of the quantum size effect.

[ pdf /
abstract ]
Abstract:
Large local optical activity in fractal aggregates of silver nanoparticles has
been observed by means of photon scanning tunneling microscopy. The effect
occurs because resonant plasmon modes in random fractals can have handedness in
spatial distribution of their amplitudes. In agreement with experimental
observations, numerical simulations show dramatic difference in dipole-moment
distributions for right- and left-circularly polarized incident light when the
cluster size is comparable with or larger than the wavelength. Variations in
the local parameter describing the circular intensity difference of scattered
light show that fractal aggregates are characterized by broad and random
distributions of chiral plasmon modes. © 2001 Optical Society of America

Abstract:
Local field distributions in random metal-dielectric films near a percolation
threshold are experimentally studied using scanning near-field optical
microscopy ~SNOM!. The surface-plasmon oscillations in such per-colation films
are localized in small nanometer-scale areas, ''hot spots,'' where the local
fields are much larger than the field of an incident electromagnetic wave. The
spatial positions of the hot spots vary with the wavelength and polarization of
the incident beam. Local near-field spectroscopy of the hot spots is performed
using our SNOM. It is shown that the resonance quality-factor of hot spots
increases from the visible to the infrared. Giant local optical activity
associated with chiral plasmon modes has been obtained. The hot spot's large
local fields may result in local, frequency and spatially selective
photomodification of percolation films.

Abstract:
Strongly enhanced second-harmonic generation ~SHG!, which is characterized by a
nearly isotropic intensity distribution, is observed for gold-glass films near
the percolation threshold. The diffuselike SHG scattering, which can be thought
of as nonlinear critical opalescence, is in sharp contrast with highly
collimated linear reflection and transmission from these nanostructured
semicontinuous metal films. Our observations, which can be explained by giant
fluctuations of local nonlinear sources for SHG due to plasmon localization,
verify recent predictions of percolation-enhanced nonlinear scattering.

Abstract:
It is shown that in cerments, with metal percolating clusters in a dielectric
host, the metal plasmon modes cn strongly couple to the dielectric vibrational
modes, optical phonons. In metal-dielectric percolation composites, the pasmon
modes are capable of strong addumulation of the electromagnetic energy in small
nanometer-sized areas, "hot-spots". The local fields in the hot spots can be
very large, leading to enhanced absorption by optical phonons of the
dielectric. In our experiments, strongly enhanced absorption by the coupled
plasmon-phonon modes has been observed in Au-Al2O3 percolation
composites.

Composites" Laser Physics v. 11 pp. 26-30 (2001)

Abstract:
Optical properties of fractal nanostructured composite materials are
considered. The fractal geom-etry results in localization of plasmon
excitations in the "hot" spots, where the local field can exceed the applied
field by several orders of magnitude. The high local fields of the localized
fractal modes result in dramatic enhancement of optical responses, making
feasible the surface-enhanced nonlinear spectroscopy of single mol-ecules and
nanocrystals. The field enhancement becomes especially large when fractals are
placed inside a microcavity. A theory for the enhanced Raman and hyper-Raman
surface-enhanced scattering in microcavity- fractal composites is developed.

Abstract:
Local field distributions are studied in random metal-dielectric films near
percolation (percolation films) and fractal aggregates of colloidal particles.
For both systems, it is shown that optical excitations are localized in small
nanometer-sized areas, "hot spots," where the local fields are much larger than
the field of an incident electromagnetic wave. The large local fields result in
giant enhancement of various optical phenomena. The surface-enhanced
white-light generation and second-harmonic generation have been obtained in
percolation films. For fractal aggregates of silver particles, a giant effect
of local optical activity has been observed. The effect is due to
surface-plasmon excitations localized on chiral-active particle configurations
in fractals

Abstract:
Optical properties of metal nanowires and nanowire composite materials are
studied experimentally and theoretically. We suggest that a nanowire composite,
constructed from parallel pairs of nanowires has both effective magnetic
permeability and dielectric permittivity negative in the visible and
near-infrared spectral ranges due to resonant excitation of surface plasmon
polaritons. Experimental results confirm excitation of surface plasmons
polaritons in periodical array of nanowires.

Abstract:
Dielectric spheres and cylinders can support high-Q modes due to internal
reflection of the light. However, small deviations of the shape of these
resonators away from symmetry lead to the onset of chaotic ray dynamics and the
resulting suppression of the mode lifetimes. We demonstrate, that in such
conditions even the regular modes are strongly affected by small deformations,
due to the phenomenon of chaos-assisted tunneling, and develop a quantitative
theory of this effect.
