摘要

构造了由四个相移范围在0～2π的电光晶体波片组成的偏振控制器,利用模拟退火法作为其反馈控制算法.仿真计算表明,该偏振控制器是无端的,在较优的控制参量下,其输出的偏振态是稳定的,光强波动小于1%.对于四波片偏振控制器,模拟退火算法的控制参量研究表明,为得到较佳的控制效果,可把内外循环次数各限制为3次,以减少处理器时间;其初温T0应取在0.1附近;温度更改常数p宜取在0.2左右;状态产生常数s对输出的稳定性影响最大,仿真说明设在0.005～0.01间为好.

Abstract

A polarization controller composed of four electro-optic crystal plates which phase delay can vary from 0 to 2π is proposed, and simulated annealing algorithm is taken on as feedback control in this controller. Simulated research shows that this controller is endless and the output polarization state is stabile while the light intensity fluctuates less than 1%. The research on control parameters indicates that the initial temperature about 0.1 and the temperature transforming function T_ k+1 =0.2T_k are required for this controller. The state generating constant s sharply influences the convergence and its better range is between 0.005 and 0.01. To reduce running time, the repeat number 9 is introduced for once search.
