D05 – Mode-Guided Infrared Absorption in Ge/SiO2 Grating for Large-Angle and Broadband Photodetection

The numerical simulation of the electromagnetic properties of the Ge/SiO2 grating structure with bottom distributed Bragg reflector. With mode guiding in Ge, the structure exhibits an absorption angle of 100° and broadband behavior from 1300 to 1500 nm.
