Abstract

Closed-form expressions explicitly relating modulation bandwidth and active length in electro-optic traveling wave modulators are presented which fully account for skin-effect electrode loss and optical-electrical wave velocities mismatch. Four operative margins have been identified where the bandwidth-length trade-off figure of merit takes simple forms.

摘要

本文提出了一种显式关联电光行波调制器调制带宽和有源长度的闭式表达式，充分考虑了趋肤效应电极损耗和光电波速度失配。确定了四个工作裕度，在此处带宽-长度折衷的优值呈现简单的形式。
