摘要

在传统的基于微环的电光开关结构中

可通过设计不同微环与直波导间的位置来实现光通信的开关功能

但其普遍存在开关电压过高的现象

浪费资源。文章利用耦合模理论、电光调制理论和微环谐振理论

应用传输矩阵理论方法

提出了一种嵌套型双波导的微环谐振电光开关的器件模型

在谐振波长为1 552 nm的情况下

对该器件进行了仿真分析。仿真结果表明

该器件模型具有非常小的开关电压（仅为1 V）

串扰<-35 dB

插入损耗<4 dB

时域响应总时间为5.33 ps

其中微环的上升时间和下降时间仅为0.25 ps。所提出的电光开关结构具有开关电压低、响应时间短和频谱带宽大的特性

能提高密集波分复用系统的性能。

Abstract

In the traditional micro-ring electro-optic switch structure

the function of switching in optical communication system is realized by designing different positions between micro-ring and direct waveguide. However

the switching voltage is so high that it wastes resources. Based on the coupled mode theory

electro-optic modulation theory

micro-ring resonance theory

and transfer matrix theory

a device model of nested micro-ring dual-channel electro-optic switch is proposed in this paper. We conduct a simulated analysis of this device at the resonant wavelength of 1 552 nm. The simulation results show that the device model has a very small switching voltage of only 1 V with crosstalk less than-35 dB and insertion loss less than 4 dB. The total time domain response is 5.33 ps with rise and fall time of only 0.25 ps. The structure has the characteristics of low switching voltage

short response time and large spectral bandwidth

which enhances the performance of dense wavelength division multiplexing system.
