摘要

本文介绍了一种基于绝缘体上硅(SOI)平台的新型双模分(de)多路复用器，该多路复用器具有宽带宽、高模式转换效率的光学特性。采用MZI结构形式的非对称定向耦合器，通过数值分析可以实现基模TE0和一级模TE1的模(解)复用器。对所提出的器件进行了数值性能分析。利用三维光束传播法(3D-BPM)结合有效指数法(EIM)进行的仿真结果表明，该器件在1550 nm波长附近±1 nm范围内，工作效率大于98%(即插入损耗小于0.1 dB)。

Two mode division (De) multiplexer based on an MZI asymmetric silicon waveguide

In this paper, we introduce a new two mode division (de) multiplexer with optical properties of broad bandwidth, high mode conversion efficiency that is built on silicon-on-insulator (SOI) platform. By using an asymmetric directional coupler in the form of an MZI structure, mode (de)multiplexer from the fundamental mode TE0 and the firstorder mode TE1 can be achieved by numerically analysis. Performance analysis of the proposed device is carried out numerically. Simulation results by using three dimension beam propagation method (3D-BPM) incorporated with effective index method (EIM) show high performance of the device with operation efficiency larger than 98% (i.e., insertion loss less than 0.1 dB) in the range ±1 nm around the wavelength of 1550 nm.
