摘要

本文设计了一种具有低串扰、低插入损耗和低功耗的数字光开关。利用有限差分光束传播法(FD- BPM)对y型结的几何形状进行了仿真和优化。确定了优化后的y结点形状为余弦s弯分支与直线分支相连的混合形状。与传统的线性y型结相比，有效折射率调制降低到26.5%，串扰值达到-34 dB。

Cosine S-bend hybrid junction digital optical switch

This paper presents the design of digital optical switch (DOS) which exhibit low crosstalk, low insertion loss and low power consumption. The geometry of Y-junction was simulated and optimized using finite difference beam propagation method (FD- BPM). The optimized Y-junction shape has been determined to be hybrid shape which consists of cosine s-bend branch connected to linear branch. Compare to conventional linear Y-junction, the effective index modulation was reduced to 26.5% to achieve -34 dB of crosstalk value.
