PHASE REVERSAL ELECTR0DE OPTIMIZATION IN BROAD-BAND ELECTR0OPTIC MODULATORS BY GENETIC ALGORITHM

本文提出了一种利用遗传算法对宽带电光调制器相位反转电极进行优化设计以获取平坦的频率响应的方法．这种遗传算法采用了直接基于电极图形的编码、交叉和变异操作．模拟计算表明，该算法对长度为1cm的电极能获得宽达100GHz的平坦的频率响应．

A new phase reversal electrode optimization by genetic algorthm for getting wide, flatfreqnency response in broad-brand electrooptic phase modulators is demonstrated. The geneticAlgorithm utilizes novel coding, crossover and mutation method directly based on electrodefigures. The simulated calculations show this method give a rather flat frequency response wider than100GHz at electrode length 1cm.
