摘要

我们提出了一种超紧凑型TE-pass偏振器，设计用于在从1400 nm到1600 nm的200 nm宽波长范围内工作，表现出出色的性能。该器件在200 nm带宽上实现了低于0.2 dB的低TE插入损耗和超过40 dB的TE模式反射损耗，以及超过30 dB的TM模式反射损耗。TM模式被有效抑制，在180nm波长范围内偏振消光比大于30db。在通信波长为1550 nm时，该偏振器在TE模式下的插入损耗低于0.2 dB，在TM模式下的消光比超过40 dB，而器件长度仅为10 μm。

Ultracompact low insertion loss TE-pass polarizer based on a bent hybrid plasmonic waveguide

We present an ultracompact TE-pass polarizer designed for operation over a broad wavelength 200 nm range from 1400 nm to 1600 nm, demonstrating outstanding performance. The proposed device achieves a low TE insertion loss of less than 0.2 dB and reflection losses exceeding 40 dB for TE mode and 30 dB for TM mode across a 200 nm bandwidth. The TM mode is effectively suppressed, resulting in a polarization extinction ratio greater than 30 dB over a 180 nm wavelength range. At the communication wavelength of 1550 nm, the polarizer maintains an insertion loss of under 0.2 dB for the TE mode and a TM extinction ratio exceeding 40 dB, all within an ultracompact device length of just 10 μm.
