摘要

【目的】

针对集成光子滤波器在密集波分复用系统中的应用，文章提出了一种基于绝缘衬底硅（SOI）上的偏振不敏感窄带切趾布拉格光栅滤波器。

【方法】

采用外脊布拉格光栅结构实现横电场基模（TE

）和横磁场基模（TM

）的相互耦合与转换，使光栅滤波器在分别输入TE

和TM

模式时，输出的滤波谱线能达到一致。同时，引入高斯分布的互补光栅错位调制结构来抑制滤波谱线中的旁瓣。此外，设计了两种不同宽度的光栅波纹，并实现了窄带滤波。

【结果】

仿真结果表明，滤波器实现了偏振不敏感，旁瓣抑制比大于22.12 dB，3-dB带宽为1.16 nm，具有良好的偏振一致性。

【结论】

文章所提工作为硅基光子回路与系统提供了一种偏振不敏感窄带滤波方案。

Abstract

【Objective】

A polarization-insensitive

narrow-band apodized Bragg grating filter based on Silicon-On-Insulator (SOI) is proposed in this paper for the application of integrated optical filters in dense wavelength division multiplexing systems.

【Methods】

The Bragg grating's corrugations are incorporated into the slab region of the ridge waveguide

enabling the coupling and conversion between the fundamental Transverse Electric (TE

) mode and the fundamental Transverse Magnetic (TM

) mode. This design ensures that the grating filter produces consistent spectral responses for both TE

and TM

mode inputs

there-by achieving polarization insensitivity. Additionally

a Gaussian-distributed complementary lateral misalignment modulation is applied to effectively suppress sidelobes in the filter spectrum. To achieve a narrow filter bandwidth

two types of grating corrugations with distinct widths are designed and implemented.

【Results】

The simulation results show that a polarization-insensitive filter with sidelobe suppression greater than 22.12 dB and a 3-dB bandwidth of 1.16 nm is numerically demonstrated.

【Conclusion】

This work provides a polarization-insensitive narrow-band filtering solution for silicon photonic circuits and systems.
