摘要

提出了一种利用窄带波导的TM模式与垂直槽波导的TE模式相匹配实现功率耦合的紧凑型偏振旋转器(PR)。优化了耦合器的横截面尺寸，使该器件成为3 μm波长的紧凑型PR，器件长度仅为2mm。我们还研究了器件在工作波长(λ) = 1.55 μm时的性能。

Design of a compact SOI polarization rotator for mid-IR application

Design of a compact polarization rotator (PR) exploiting power coupling through phase matching between the TM mode of a strip waveguide (WG) and TE mode of a vertical slot WG is presented. Optimized cross sectional dimensions of the coupler have been achieved to use this device as a compact PR at 3 μm wavelength with device length of just 2 mm. We also investigate the device performance at the operating wavelength (λ) = 1.55 μm.
