Atomic, Molecular, and Optical Physics
Overview
We have experimental, theoretical, or computational programs in nanophotonics, nanoplasmonics, negative refractive index materials, femtosecond spectroscopy, organic photonics, and optical tweezers trapping of nanoparticles. A new effort in femtosecond spectroscopy is studying high speed dynamics and nonlinear responses in semiconductor nanostructures.
Organic Photonics and Electronics
Oksana G. OstroverkhovaThe Organic Photonics and Electronics Group explores light-matter interactions in organic optical materials. Of particular interest are the basic physics of exciton and photogenerated charge carrier dynamics in organic semiconductors and inorganic-organic polymer nano-composites, photophysical and electronic properties of individual molecules in studies of complex environments, and applications of organic molecules in nanoscale electronic and all-optical devices.
Electromagnetism of metamaterials
Viktor A. Podolskiyviktor.podolskiy@physics.oregonstate.edu (541)737-1702 WNGR 401A
Our research focuses on the electromagnetic properties of nano- and micro-structured composites, negative refractive index materials, nanophotonics, and nanoplasmonics.
Femtosecond Spectroscopy in Semiconductors
Yun-Shik Leeleeys@physics.orgeonstate.edu (541)737-5057 WNGR 415
Yun-Shik Lee's research focuses on terahertz spectroscopy and ultrafast carrier dynamics in semiconductors using femtosecond lasers. Major activities are (i) development of new schemes to manipulate teraherz (THz) pulses using optical rectification in nonlinear crystals (LiNbO3 , ZnTe, and GaAs), (ii) optical and THz measurements at cryogenic temperature to investigate exciton dynamics in semiconductor quantum wells (QWs) under strong THz fields, and (iii) study of large amplitude motions in proteins via THz time-domain spectroscopy (THz-TDS) investigating the feasibility of using THz spectroscopy for biosensing and analysis.
Optical trapping and laser spectroscopy
