摘要

在分析马赫-曾德尔干涉仪（MZI）基本结构的基础上，定义了二种开关形式，以二者作为结构单元，采用Banyan网络结构，提出了一种新型的可实现1：k(k＞1)多路连接的波导矩阵光开关，以2×2、4×4矩阵光开关为例，给出了该类光开关的结构和功能。对MZI结构进行了性能模拟和优化，分析了Banyan网络中交叉连接损耗与交叉角度的关系，并由此对整个开关的插入损耗进行了分析。基于PLC技术制作出相应的MZI开关单元及2×2、4×4波导SiO2光开关实物，测试结果与仿真结果基本吻合，开关时间均小于1ms，该类光开关能够很好地实现多路开关的功能。

Abstract

On analysis of the basic structure of Mach-Zehnder interferometer (MZI)

two switch units were defined. A new type optical matrix switch based on Banyan network was proposed

and the multiport interconnection 1:k (k＞1) can be realized with two types of Mach-Zehnder interferometer (MZI) units. Taking the 2×2 and 4×4 optical matrix switches for example

the constructions and characteristics of this new type optical matrix switch were provided. With the optimization and the design of the MZI construction

the influences of the intersection angles among the waveguide links and the excess loss of the MZI units on the total optical loss of system are studied

and the insertion loss of systems is discussed. Based on planar lightwave circuit (PLC) technology

SiO2-based MZI units

2×2 and 4×4 optical matrix switch were fabricated. A basic agreement between experimental results and theoretical calculation was obtained and the response time of less than 1 ms was obtained

then the multiport switch function fulfilled.
