摘要

本文提出了一种基于锗光子晶体腔的锗锗光电探测器设计方案。计算模型表明，在较宽的中波红外光谱范围内，吸收效率有所提高。在可控色散工程条件下，获得了较高的光机械耦合增益(>3.6e-4 W/m2/K)。

Design of a SiGe Waveguide Photodetector with PxC Cavity for Broadband MWIR Sensing

In this work, SiGe photodetector design with a Ge-phoxonic crystal cavity on top is proposed. The computational modelling shows enhancement in the absorption efficiency over a broad range of midwave infrared spectrum. A high optomechanical coupling gain (>3.6e-4 W/m2/K) with controlled dispersion engineering is observed.
