The strikingly colorful world of insects is in large part the result of optical interference produced by the interaction of light with precisely ordered\, periodic bio-polymeric structures\, incorporated into their exoskeletons. Such structural colors have recently gained tremendous interest for the use as photonic crystals with promising potential for energy and information technology applications.

II-VI MSs Zn1-xMnxTe and Zn1-xMnxSe exhibit their absorption edges at 428-544 nm and 428-458 nm\, respectively. The edge is not so influenced by the Mn concentration\, as is typically observed in Cd1-xMnxTe. We have confirmed that the Faraday rotation F in the ZnMnTe films deposited on quartz glass (QG) substrates is large near the absorption edge.

The former is dominated by optical methods\, emerging “life on a chip” systems and the versatile magnetic resonance imaging technology. The latter remains an ongoing challenge.
