摘要

采用TriPleX技术制造的基于氮化硅(Si3N4)的光子电路已被证明是低损耗的，同时占用相对较小的占地面积。我们设计并模拟了c波段5 nm波长范围内通道间距为50 GHz的阵列波导光栅(AWG)和FSR为50 GHz的微环谐振器(MRR)，作为集成的Si3N4波导微光谱仪的构建模块。仿真结果表明，AWG的损耗为2 - 4db, MRR的分辨率为sub-GHz。

Design and Simulation of a Si3N4 Sub-GHz Resolution Integrated Micro-Spectrometer

Silicon Nitride (Si3N4) based photonics circuits fabricated using TriPleX technology have proven to be low-loss while occupying relatively small footprint. We designed and simulated an Arrayed Waveguide Grating (AWG) with 50 GHz channel spacing over 5 nm wavelength range in the C-band together with a Micro Ring Resonator (MRR) with an FSR of 50 GHz as integrated building blocks of a micro-spectrometer using Si3N4 waveguides. Simulation results reveal 2 – 4 dB loss for AWG and sub-GHz resolution for MRR.
