The spectrum of rigorously nonspreading w... Focal plane tuning in wide-field-of-view microscope with Talbot pattern illumination [作者：Wu, JG; Zheng, GA; Li, Z; Yang, CH,期刊：OPTICS LETTERS, 页码：2179-2181 , 文章类型： Article，,卷期：2011年36-12] We have developed a focal plane tuning technique for use in focus-grid-based wide-field-of-view microscopy (WFM). In WFM, the incidence of a collimated beam on a mask with a two-dimensional grid of aperture produced the ...

Instability in the melt and concomitant opacity of fibers were observed at source concentrations higher th... Group velocity manipulation in active fibers using mutually modulated cross-gain modulation: from ultraslow to superluminal propagation [作者：Qian, K; Zhan, L; Zhang, L; Zhu, ZQ; Peng, JS; Gu, ZC; Hu, X; Luo, SY; Xia, YX,期刊：OPTICS LETTERS, 页码：2185-2187 , 文章类型： Article，,卷期：2011年36-12] We propose and experimentally demonstrate the propagation of slow/fast light in an erbium-doped fiber (EDF) using mutually modulated cross-gain modulation. The group velocity of the light signal can be manipulated by the... Modulation-free optical locking of an external-cavity diode laser to a filter cavity [作者：Hayasaka, K,期刊：OPTICS LETTERS, 页码：2188-2190 , 文章类型： Article，,卷期：2011年36-12] Optical locking to a filter cavity is an effective method to eliminate the limitations of an external-cavity diode laser, such as broad spontaneous emission backgrounds and frequency jitters. Stable operation of the opti... Actively mode-locked fiber laser using a deformable micromirror [作者：Fabert, M; Kermene, V; Desfarges-Berthelemot, A; Blondy, P; Crunteanu, A,期刊：OPTICS LETTERS, 页码：2191-2193 , 文章类型： Article，,卷期：2011年36-12] We present what we believe to be the first fiber laser system that is actively mode-locked by a deformable micromirror. The micromirror device is placed within the laser cavity and performs a dual function of modulator a... Depth from structured defocus that is independent of the object reflectivity function [作者：Birch, P; Buchanan, A; Young, R; Chatwin, C,期刊：OPTICS LETTERS, 页码：2194-2196 , 文章类型： Article，,卷期：2011年36-12] Depth from defocus using structured light is a useful optical metrology technique since the camera and projector can be placed on the same optical axis and it can cope with depth discontinuities. However, the technique c... Fiber refractometer based on a fiber Bragg grating and single-mode-multimode-single-mode fiber structure [作者：Wu, Q; Semenova, Y; Yan, BB; Ma, YQ; Wang, PF; Yu, CX; Farrell, G,期刊：OPTICS LETTERS, 页码：2197-2199 , 文章类型： Article，,卷期：2011年36-12] A refractive index (RI) sensor based on a novel fiber structure that consists of a single-mode-multimode-single-mode(SMS) fiber structure followed by a fiber Bragg grating was demonstrated. The multimode fiber in the SMS... Multifocus with small size, uniform intensity, and nearly circular symmetry [作者：Guo, HM; Dong, XM; Weng, XY; Sui, GR; Yang, N; Zhuang, SL,期刊：OPTICS LETTERS, 页码：2200-2202 , 文章类型： Article，,卷期：2011年36-12] We investigate in detail the focusing properties of the composite vector beam (CVB) composed of two orthogonally linearly polarized beams with inhomogeneous polarization modulation. By optimizing the modulation factor, a... High quality factor nitride-based optical cavities: microdisks with embedded GaN/Al(Ga)N quantum dots [作者：Mexis, M; Sergent, S; Guillet, T; Brimont, C; Bretagnon, T; Gil, B; Semond, F; Leroux, M; Neel, D; David, S; Checoury, X; Boucaud, P,期刊：OPTICS LETTERS, 页码：2203-2205 , 文章类型： Article，,卷期：2011年36-12] We compare the quality factor values of the whispering gallery modes of microdisks (mu-disks) incorporating GaN quantum dots (QDs) grown on AlN and AlGaN barriers by performing room temperature photoluminescence (PL) spe... Analytical properties of the plasmon decay profile in a periodic metal-nanoparticle chain [作者：Fung, KH; Tang, RCH; Chan, CT,期刊：OPTICS LETTERS, 页码：2206-2208 , 文章类型： Article，,卷期：2011年36-12] We show that the spatial decay of plasmons in a periodic metal-nanoparticle chain is composed of exponential and power-law decays.
