Paper Abstract

A general structure of Ge-on-Si Resonant cavity enhanced (RCE) PIN photodetectors with modified top and bottom mirrors operation at 1.55μm is presented. Resonating mirrors with higher reflectance are obtained. Different cases on the relationship of quantum efficiency and wavelength are discussed in detail. The number of Si-SiO2 layers in top and bottom mirrors for the highest quantum efficiency is analyzed. The frequency response considering both the transit time and the capacitance with different device areas is also simulated. These results offer a complete guideline for designing and fabricating a high speed, high quantum efficiency Ge-on-Si RCE PIN device.
