Optical resonance in inhomogeneous parity-time symmetric systems

We show that inhomogeneous waveguides of slowly varied parity-time[PT]symmetry support localized optical resonances.The resonance is closely related to the formation of exceptional points separating exact and broken PT phases.Salient features of this kind

500 GHz宽带双偏振光学频率梳的产生

提出了一种基于光电反馈产生500 GHz宽带双偏振光学频率梳的方案.该方案基于光电环路反馈1550 nm垂直腔面发射激光器,采用自旋反转模型,利用四阶龙格-库塔算法数值仿真研究了光电反馈参数对光学频率梳特性的影响.研究结果表明:通过光电反馈参数的调节可以控制1550 nm垂直腔面发射激光器输出的偏振状态,可实现Y偏振和X偏振光学频率梳的转换.此外,研究发现,在特定的光电反馈参数条件下,可获得Y偏振和X偏振同时存在的双偏振光学频率梳.并且在一定的光电反馈参数范围内,两个偏振方向的光学频率梳的光谱带宽都会随着

Highly twisted M-line of a vortex beam due to the coupling of ultrahigh-order modes

In modern optics,particular interest is devoted to the phase singularities that yield complicated and twisted phase struc-tures by photons carrying optical angular momentum.In this paper,the traditional M-line method is applied to a vortex beam[VB]by a sy

Experimental observation of transient mode-locking in the build-up stage of a soliton fiber laser

In this paper,we demonstrated a series of short-living mode-locking[ML]states[each lasting a few to a hundred micro-seconds]that happened before a fiber laser reached a steady ML state.With time-stretched dispersion Fourier transform spectroscopy,a rich d

大陡度透镜表面膜层折射率均匀性分析

集成电路与光刻机系统中通常会设计并使用很多小曲率半径的大陡度透镜,以实现大数值孔径,这对镀制于其表面的紫外薄膜的性能提出了很高的要求.本文分析了行星夹具转动过程中大陡度凸透镜从中心到边缘位置的薄膜沉积角度的变化规律,研究了 MgF2膜层的折射率随沉积角度的变化规律,明确了大陡度凸透镜从中心到边缘位置的膜层折射率不均匀性对深紫外增透膜的影响.针对小曲率半径大陡度凸透镜表面的膜层沉积特性,通过升高基底温度提高了折射率分布的均匀性,为大陡度透镜膜层折射率不均匀性修正提供了理论和实验依据.
