In this paper  phase fluctuation characteristics of the beam transmitted through the fibers with no amplification are presented. The results show that the phase fluctuation frequencies of the laser beam transmitted through these three kinds of fibers are mainly in the range of 100-200Hz  100-300Hz and 80-400Hz respectively in normal laboratory environment. The phase fluctuation frequencies of the laser beam transmitted through the DCF  in cases of when the environment temperature is changing  a constant pressure is applied to the fiber and when vibration is applied  are mainly in the range of 100-600Hz  100Hz-300Hz and 100-500Hz respectively. In the same cases  for the LMF  the phase fluctuation frequencies are mainly in the range of 150-600Hz  100-400Hz and 100-1000Hz  respectively. It indicates that for realizing phase stabilization  the bandwidth of any potential phase control2 system has to be in the range of a few kilohertz.   Distribution of entangled photon pairs over few mode fibers 会议论文 Asia Communications and Photonics Conference, ACPC 2016, Wuhan, China, 2016 作者:  Cui, Liang;  Su, Jie;  Li, Xiaoying 收藏  |  浏览/下载：0/0  |  提交时间：2019/11/21 Highly sensitive twist sensor based on CO2-laser-induced long period grating in few mode fibers 会议论文 Hong kong, November 19, 2015 - November 23, 2015 作者:  Feng, Yuan-Hua[1];  Ran, Yang[1];  Sun, Li-Peng[1];  Li, Zhaohui[1] 收藏  |  浏览/下载：0/0  |  提交时间：2019/12/17
