摘要
基于超对称的概念,在超对称光学波导对的基础上设计出超对称三波导结构,并引入斜波导作为绝热耦合中间介质,以解决超对称波导器件的定向模式耦合问题。通过束传播方法模拟了耦合过程,讨论了斜波导倾斜角对耦合效率的影响,并得出了最佳的耦合条件。最后设计了一种基于超对称波导结构的三通道模分复用器,为高速短程光复用/解复用交互技术提供了新思路。
Abstract
Based on the concept of supersymmetry, three supersymmetric waveguides are designed on the basis of supersymmetric optical waveguide pairs. To solve the directional mode coupling problem of supersymmetric waveguides, we insert a slant waveguide in the three supersymmetric waveguides as an adiabatic coupling medium. The coupling process is numerically simulated by beam propagation method (BPM). The effect of the slant waveguide's angle on coupling efficiency is discussed and the optimal coupling condition is obtained. Finally, a three-channel mode division multiplexer based on supersymmetric waveguides structure is designed, which provides a new idea for high-speed short-range optical multiplexing/demultiplexing technology.
