[作者:Ngo, TP; El Kurdi, M; Checoury, X; Boucaud, P; Damlencourt, JF; Kermarrec, O; Bensahel, D,期刊:Applied Physics Letters, 页码:41112-41112 , 文章类型: Article,,卷期:2008年93-24]
- Germanium on insulator on silicon substrates can be obtained by the growth of a SiGe layer on silicon on insulator followed by a condensation at high temperature and a Ge epitaxial growth. We show that these substrates c...
- Interplay among multidressed four-wave mixing processes - art. no. 241101

- We report our experimental studies of interplays between four-wave mixing (FWM) processes in multidressed two- and three-level atomic systems. The Autler-Townes splitting of the FWM signal within the electromagnetically ...
- Formation of X-waves at fundamental and harmonics by infrared femtosecond pulse filamentation in air - art. no. 241104
[作者:Xu, H; Xiong, H; Fu, YX; Yao, JP; Zhou, ZH; Cheng, Y; Xu, ZZ; Chin, SL,期刊:Applied Physics Letters, 页码:41104-41104 , 文章类型: Article,,卷期:2008年93-24]
- We experimentally observe the formation of X-waves at fundamental, third harmonic, and fifth harmonic wavelengths by infrared (central wavelength at similar to 1500 nm) femtosecond laser pulse filamentation in air. By fi...
- Highly confined mode above the light line in a two-dimensional photonic crystal slab - art. no. 241105
[作者:Xu, T; Wheeler, MS; Nair, SV; Ruda, HE; Mojahedi, M; Aitchison, JS,期刊:Applied Physics Letters, 页码:41105-41105 , 文章类型: Article,,卷期:2008年93-24]
- We found that certain modes above the light line can satisfy total internal reflection in a two-dimensional photonic crystal slab, resulting in negligible vertical leakage. A heterogeneous cavity utilizing such a mode wa...
