Diagnostics of the topological charge of optical vortex by a phase-diffractive element被引量：6
《Chinese Optics Letters》2016年第8期17-21,共5页付时尧 王彤璐 高衍 高春清 
supported by the National Basic Research Program of China(973 program)under Grant Nos.2014CB340002 and 2014CB340004
A phase-diffractive optical element is designed to measure the topological charge of optical vortices. We use the scalar diffraction theory to calculate the far-field diffraction patterns. The simulation results show ...

Rotary propagation characteristics of light in multimodesingle mode-multimode fiber structures using ray tracing method
《Optoelectronics Letters》2015年第4期294-297,共4页郜洪云 吴紫薇 许哲雄言 黎敏 
supported by the National Natural Science Foundation of China(No.61177076);the Fundamental Research Funds for the Central Universities(Nos.2013-Ia-038 and 2013-Ia-006)
The mode theory is the main way to study the propagation characteristics of light in fiber so far,but it is not suitable for analysis of light in duct.By using ray-tracing method,the rotary propagation characteristics...

Photons　in　the　Non－uniform　Optical　Waveguide　Propagate　along　z－axis　in　Spiral　Form
《Semiconductor Photonics and Technology》1996年第3期184-188,共5页ZHANG Jinwei(Jinan University, Guangzhou 510632, CHN) 
This paper gives the strict solution of optical field equation in the optical waveguides with parabolic profiles. It shows that the photons in the non-uniform optical waveguide propagate along z-axis in spiral form, j...
