- Optimization of LiNbO(3) photonic crystals: toward 3D LiNbO(3) micro-components
[作者:Courjal, N; Dahdah, J; Ulliac, G; Sevillano, P; Guichardaz, B; Baida, F,期刊:OPTICS EXPRESS, 页码:23008-23016 , 文章类型: Article,,卷期:2011年19-23]
- We report easy-to-implement techniques to improve the reflectivity of LiNbO(3) photonic crystals within the photonic bandgap. Firstly, we show that widening the channel waveguides confines the optical modes in the vertic...
- Spatially selective photonic crystal enhanced fluorescence and application to background reduction for biomolecule detection assays
[作者:Chaudhery, V; Huang, CS; Pokhriyal, A; Polans, J; Cunningham, BT,期刊:OPTICS EXPRESS, 页码:23327-23340 , 文章类型: Article,,卷期:2011年19-23]
- By combining photonic crystal label-free biosensor imaging with photonic crystal enhanced fluorescence, it is possible to selectively enhance the fluorescence emission from regions of the PC surface based upon the densit...
- High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit
[作者:Marshall, ARJ; Ker, PJ; Krysa, A; David, JPR; Tan, CH,期刊:OPTICS EXPRESS, 页码:23341-23349 , 文章类型: Article,,卷期:2011年19-23]
- High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of ...
- Enhanced electroluminescence of a-plane InGaN light emitting diodes grown on oxide-patterned r-plane sapphire substrates
[作者:Hwang, SM; Song, H; Seo, YG; Son, JS; Kim, J; Baik, KH,期刊:OPTICS EXPRESS, 页码:23036-23041 , 文章类型: Article,,卷期:2011年19-23]
- We report on the new fabrication method of a-plane InGaN light emitting diodes (LEDs) using the epitaxy on patterned insulator on sapphire substrate (EPISS). Cathodoluminescence spectrum of the fully coalesced a-plane Ga...
- Efficient terahertz en-face imaging
[作者:Katletz, S; Pfleger, M; Puhringer, H; Vieweg, N; Scherger, B; Heinen, B; Koch, M; Wiesauer, K,期刊:OPTICS EXPRESS, 页码:23042-23053 , 文章类型: Article,,卷期:2011年19-23]
- In this work, we develop a pulsed terahertz imaging system in reflection geometry, where due to scanning of the terahertz beam neither the sample nor the emitter and detector have to be moved. We use a two mirror galvano...
- Optimal conditions for using the binary approximation of continuously self-imaging gratings
[作者:Piponnier, M; Druart, G; Guerineau, N; de Bougrenet, JL; Primot, J,期刊:OPTICS EXPRESS, 页码:23054-23066 , 文章类型: Article,,卷期:2011年19-23]
- Diffractive Optical Elements (DOE), that generate a propagation-invariant transverse intensity pattern, can be used for metrology and imaging application because they provide a very wide depth of focus. However, exact im...
