Broadband InGaAs/InP Photodiode Array

SSSC proposes 25 x 25 element InGaAs/InP photodiode arrays with quantum efficiencies greater than 80% for the entire wavelength range between 400 nm and 1650 nm. Individual photodiodes are addressable and have electrical bandwidths in excess of 3 GHz.Using internal reflection properties, spectral responses can be tuned to provide more than 90% quantum efficiency at specific wavelengths. These arrays will enable a single receiver or camera to perform multiple functions simultaneously. Low costphotodiode arrays with a broad wavelength range of sensitivity enable the development of compact receivers and cameras that can perform multiple functions simultaneously. This includes machine vision systems that perform object recognition and position,bio-chemical detection and monitoring systems, and enhanced vision systems for commercial pilots and surgeons. Other areas that will benefit include optical communications, automotive, and scientific/astronomy.
