Effect of circular dichroism in chiral photonic crystal liquid with enclosed defect layer inside

Gevorgyan A.H., Kocharian A.N., Vardanyan G.A., California State University Los Angeles, US

The photonic crystals of artificial and self-organizing structures with spatial periodic changes in dielectric and magnetic properties have attracted considerable interest recently due to unusual physical properties and wide practical applications. The chiral periodic structure [...]

Label-free and Real-Time Photonic Band-Gap Silica Nanosensor

Chyan J.Y., Yang S.C., Yeh J.A., National Tsing Hua University, TW

A photonic band-gap nanosensor based on porous silica is proposed in the study. The photonic band-gap silica nanosensor is easy to fabricate and simple to use. Its optical characteristics can be easily modulated by electrochemical [...]

Influences of the Surrounding Materials on CdTe Quantum Dots within Self-Assembled Thin Films

Gardner H.C., Bertoni C., Gallardo D.E., Dunn S., Cain M.G., National Physical Laboratory, UK

Semiconductor nanocrystals (NCs) have been successfully incorporated into nanostructured light emitting devices (NLEDs) and now promise applications in electronic, medical and telecommunication industries. To better understand and further develop NLEDs it is important to consider [...]

A Nanoporous Silicon 1-D Photonic Band Gap Microcavity as a Selective Optical Sensor

Chappel S., DeLouise L., Gersten B., Queens College, US

A nanoporous silicon (pSi) one dimensional photonic band gap (1-D PBG) with a microcavity was prepared for selective sensing in the optical regime. The cavity resonance of the localized mode was tuned by the thickness [...]
