摘要

硅光子系统具有很强的双折射特性，这使得偏振管理至关重要。通过完整的3d fdtd仿真，我们展示了一种基于倾斜亚波长光栅的低损耗高消光比tm通偏振器，该偏振器将TE0模式反射到TE1模式，带宽为150 nm。

High performance TM-pass polarizer via subwavelength grating bandgap engineering

Silicon photonics systems exhibit a strong birefringence which makes polarization management critical. Here we demonstrate, with full 3D-FDTD simulations, a low-loss and high-extinction ratio TM-pass polarizer based on tilted subwavelength gratings that reflects the TE0 mode into the TE1 mode, with a 150 nm bandwidth,
