摘要
分析了硅基十字缝隙波导(SCSW)偏振敏感的原因,计算了不同偏振态下SCSW 的有效折射率和单模工作条件,分析发现通过合理的设计单模SCSW 的结构,可以达到偏振不敏感。提出并模拟了基于SCSW 的具有偏振无关特性的微环形谐振腔。该谐振腔的半径为3.7 μm,偏振无关的工作区域大约64 nm,自由光谱范围大约35 nm。
Abstract
Origin of polarization sensitivity of the silicon cross-slot waveguide (SCSW) is analyzed. The effective refractive indices as well as the single-mode-operation conditions of SCSWs for different polarization states are calculated. A single-mode SCSW can be polarization-insensitive if its structure is designed dedicated. A polarization-independent micro-ring resonator with 3.7μm radius based on a polarization-insensitive SCSW is proposed and simulated. The polarization-independent working bandwidth of the micro-ring resonator is about 64 nm, and the free spectral range is about 35 nm.
