A compact microring resonator (MRR) and its implementation for polarization rotation-based all-optical switching are proposed. The polarization rotation has been achieved by enhancing geometry-induced birefringence of the device and with the insertion of polarization rotator in the race-track-shaped MRR. The proposed device has been modeled using Jones matrix and the finite-difference time-domain simulation method. The insertion loss and the extinction ratio have been found to be −0.13 and 19.39 dB, respectively.

微环谐振器偏振旋转的实现及其在全光开关设计中的应用

提出了一种紧凑型微环谐振器 (MRR) 及其实现基于偏振旋转的全光切换。偏振旋转是通过增强器件的几何诱导双折射和在跑道形 MRR 中插入偏振旋转器来实现的。所提出的设备已使用琼斯矩阵和有限差分时域仿真方法进行建模。已发现插入损耗和消光比分别为 -0.13 和 19.39 dB。
