- Light localization in nonuniformly randomized lattices
[作者:Kartashov, YV; Konotop, VV; Vysloukh, VA; Torner, L,期刊:OPTICS LETTERS, 页码:286-288 , 文章类型: Article,,卷期:2012年37-3]
- We address Anderson localization of light in disordered optical lattices where the disorder strength varies across the transverse direction. Such variation changes the preferred domains where formation of localized eigen...
- Phase-matched third-harmonic generation in highly germanium-doped fiber
[作者:Bencheikh, K; Richard, S; Melin, G; Krabshuis, G; Gooijer, F; Levenson, JA,期刊:OPTICS LETTERS, 页码:289-291 , 文章类型: Article,,卷期:2012年37-3]
- Phase-matched third-harmonic generation is demonstrated in a germanium-doped optical fiber. Green light at 514.4 nm is generated in an LP03 mode when a pump field at similar to 1543.3 nm is launched into the fiber in the...
- Terahertz bandpass filters using double-stacked metamaterial layers
[作者:Zhu, YH; Vegesna, S; Kuryatkov, V; Holtz, M; Saed, M; Bernussi, AA,期刊:OPTICS LETTERS, 页码:296-298 , 文章类型: Article,,卷期:2012年37-3]
- Bandpass filters are reported based on double-stacked metamaterial layers separated by an air gap for operation at terahertz frequencies. Several stacking configurations were investigated designed for a similar to 0.5 TH...
- Ultrahigh infrared normal spectral emissivity of microstructured silicon coating Au film
[作者:Feng, GJ; Li, Y; Wang, Y; Li, P; Zhu, JT; Zhao, L,期刊:OPTICS LETTERS, 页码:299-301 , 文章类型: Article,,卷期:2012年37-3]
- We studied infrared normal spectral emissivity on quasi-periodic microstructured silicon, which was prepared by femtosecond laser irradiation in SF6 ambient gas, coated with 100 nm thick Au thin film. The observed emissi...
- Widely tunable and ultrasensitive leaky-guided multimode fiber interferometer based on refractive-index-matched coupling
[作者:Lee, CL; Lin, KH; Lin, YY; Hsu, JM,期刊:OPTICS LETTERS, 页码:302-304 , 文章类型: Article,,卷期:2012年37-3]
- This investigation presents a simple, widely tunable, and ultrasensitive sensor that is based on a leaky-guided multimode fiber interferometer (MMFI) operated under refractive-index-matched coupling. By use of a material...
- Longitudinal-differential interferometry: direct imaging of axial superluminal phase propagation
[作者:Kim, MS; Scharf, T; Etrich, C; Rockstuhl, C; Peter, HH,期刊:OPTICS LETTERS, 页码:305-307 , 文章类型: Article,,卷期:2012年37-3]
- We introduce and demonstrate a new interferometric method called longitudinal-differential (LD) interferometry, which measures the spatially resolved phase difference of the scattered field by an object relative to the i...
- Coherence-polarization mixing in resonance gratings
[作者:Vartiainen, I; Saastamoinen, T; Tervo, J; Kuittinen, M,期刊:OPTICS LETTERS, 页码:314-316 , 文章类型: Article,,卷期:2012年37-3]
- We show, using rigorous diffraction theory, that resonance gratings can be used to transfer partial spatial correlation to partial polarization even if the incident light beam is fully polarized. The phenomenon is based ...
- Compact optical microfiber phase modulator
[作者:Zhang, XL; Belal, M; Chen, GY; Song, ZQ; Brambilla, G; Newson, TP,期刊:OPTICS LETTERS, 页码:320-322 , 文章类型: Article,,卷期:2012年37-3]
- A compact optical microfiber phase modulator with MHz bandwidth is presented. A micrometer-diameter microfiber is wound on a millimeter-diameter piezoelectric ceramic rod with two electrodes. When a voltage is applied to...
- Reflective fiber-optic refractometer based on a thin-core fiber tailored Bragg grating reflection
[作者:Ma, Y; Qiao, XG; Guo, T; Wang, RH; Zhang, J; Weng, YY; Rong, QZ; Hu, ML; Feng, ZY,期刊:OPTICS LETTERS, 页码:323-325 , 文章类型: Article,,卷期:2012年37-3]
- A novel reflective refractometer based on a thin-core fiber (TCF) sandwiched between a leading single-mode fiber (SMF) and a fiber Bragg grating (FBG) imprinted SMF stub was demonstrated. The reflection from the fiber st...
