摘要
采用光束传播法(BPM)计算了交叉型TE/TM模分离器的偏振串音(crosstalk)。通过结构参数的优化,理论计算的偏振串音为-23.7 dB(TM)和-22.8 dB(TE)。同时制成相应的器件,测试结果表明,理论计算与实验是一致的。
Abstract
The polarization crosstalk of a TE/TM mode splitter based on a Ti:LiNbO 3 waveguide crossing is deduced by using a beam propagation method(BPM). Optimizing the configuration of the device, the theoretial crosstalk is less than -23.7 dB(TM) and -22.8 dB(TE). The crosstalks of developed splitters have been measured, and the experimental results are consistent with theory.
