- We report a continuous-wave (cw) single frequency Nd:YAG blue laser at 473 nm end-pumped by a laser diode. A ring laser resonator was designed, the frequency doubling efficiency and the length of nonlinear crystal were o...
- Planar high-numerical-aperture low-loss focusing reflectors and lenses using subwavelength high contrast gratings
[作者:Lu, FL; Sedgwick, FG; Karagodsky, V; Chase, C; Chang-Hasnain, CJ,期刊:OPTICS EXPRESS, 页码:12606-12614 , 文章类型: Article,,卷期:2010年18-12]
- We propose planar, high numerical aperture (NA), low loss, focusing reflectors and lenses using subwavelength high contrast gratings (HCGs). By designing the reflectance and the phase of non-periodic HCGs, both focusing ...

- The ability of diffuse reflectance spectroscopy to extract quantitative biological composition of tissues has been used to discern tissue types in both pre-clinical and clinical cancer studies. Typically, diffuse reflect...
- Simultaneous observation of superluminal and slow light propagation in a nested fiber ring resonator
[作者:Wang, JF; Zhang, YD; Zhang, J; Cai, YX; Zhang, XA; Yuan, P,期刊:OPTICS EXPRESS, 页码:13180-13186 , 文章类型: Article,,卷期:2010年18-12]
- We observe both superluminal and slow light propagation simultaneously in a nested fiber ring resonator. The two outputs of the resonator exhibit different absorption characteristics that produce opposite dispersion perf...
- Flat and low dispersion in highly nonlinear slot waveguides
[作者:Zhang, L; Yue, Y; Xiao-Li, YY; Wang, J; Beausoleil, RG; Willner, AE,期刊:OPTICS EXPRESS, 页码:13187-13193 , 文章类型: Article,,卷期:2010年18-12]
- We propose highly nonlinear slot waveguides with flat and low dispersion over a wide wavelength range. Si nano-crystal and chalcogenide glass are considered as slot materials. Over a 244-nm bandwidth, dispersion of 0 +/-...
- Diode-end-pumped passively Q-switched 1.33 mu m Nd:Gd3AlxGa5-xO12 laser with V3+: YAG saturable absorber
[作者:Zhang, BT; Yang, JF; He, JL; Huang, HT; Liu, SD; Xu, JL; Liu, FQ; Zhi, YC; Tao, XT,期刊:OPTICS EXPRESS, 页码:12052-12058 , 文章类型: Article,,卷期:2010年18-12]
- We demonstrated the 1.33 mu m laser performance with Nd:Gd(3)AlxGa(5-x)O(12) (x = 0.94) (Nd:GAGG) laser crystals for the first time. Continuous-wave (cw) output power of 2.45 W was obtained with the optical-optical conve...
- 3D In Vivo optical coherence tomography based on a low-voltage, large-scan-range 2D MEMS mirror
[作者:Sun, JJ; Guo, SG; Wu, L; Liu, L; Choe, SW; Sorg, BS; Xie, HK,期刊:OPTICS EXPRESS, 页码:12065-12075 , 文章类型: Article,,卷期:2010年18-12]
- 3D in vivo optical imaging on a mouse has been obtained using a 2D MEMS mirror for lateral scanning in a time-domain optical coherence tomography (OCT) system. The MEMS mirror aperture size is 1 x 1 mm(2), and the device...
- Measurements of polarimetric sensitivity to hydrostatic pressure, strain and temperature in birefringent dual-core microstructured polymer fiber
[作者:Szczurowski, MK; Martynkien, T; Statkiewicz-Barabach, G; Urbanczyk, W; Webb, DJ,期刊:OPTICS EXPRESS, 页码:12076-12087 , 文章类型: Article,,卷期:2010年18-12]
- We experimentally characterized a birefringent microstructured polymer fiber of specific construction, which allows for single mode propagation in two cores separated by a pair of large holes. The fiber exhibits high bir...
