Based on the smoothness assumption, the method employs a set of Zernike polynomials (ZPs) to fit the ph...

The MMI could operate at an optical fiber communicatio... Differential matrix formalism for depolarizing anisotropic media [作者：Ossikovski, R,期刊：OPTICS LETTERS, 页码：2330-2332 , 文章类型： Article，,卷期：2011年36-12] Azzam's differential matrix formalism [J. Opt. Soc. Am. 68, 1756 (1978)], originally developed for longitudinally inhomogeneous anisotropic nondepolarizing media, is extended to include depolarizing media. The generaliza... Angularly separated harmonic generation from intense laser interaction with blazed diffraction gratings [作者：Yeung, M; Zepf, M; Geissler, M; Dromey, B,期刊：OPTICS LETTERS, 页码：2333-2335 , 文章类型： Article，,卷期：2011年36-12] We made numerical simulations of the generation of narrowband beams of extreme ultraviolet radiation from intense laser interaction with a blazed grating surface. Strong fifth harmonic emission into its blazed diffractio... Femtosecond filamentation in argon and higher-order nonlinearities [作者：Wang, ZX; Zhang, CJ; Liu, JS; Li, RX; Xu, ZZ,期刊：OPTICS LETTERS, 页码：2336-2338 , 文章类型： Article，,卷期：2011年36-12] We numerically investigate the femtosecond filamentation dynamics in argon by considering the higher-order nonlinearities measured by a recent experiment. Our result indicates that, instead of plasma, these higher-order ... Subwavelength localization of near fields in coupled metallic spheres for single-emitter polarization analysis [作者：Li, PN; Tsao, HH; Huang, JS; Huang, CB,期刊：OPTICS LETTERS, 页码：2339-2341 , 文章类型： Article，,卷期：2011年36-12] We numerically demonstrate selective near-field localization determined by the polarization state of a single emitter coupled to a plasmonic nanocluster. Seven gold nanospheres are carefully arranged such that up to 10 p... Characterization of vector diffraction-free beams [作者：Wang, TT; Yang, SY; Li, CF,期刊：OPTICS LETTERS, 页码：2342-2344 , 文章类型： Article，,卷期：2011年36-12] It is observed that a constant unit vector denoted by I is needed to characterize a complete orthonormal set of vector diffraction-free beams. The previously found diffraction-free beams are shown to be included as speci...
