Novel high performance multispectral photodetector and its performance
Banpil Photonics has developed a novel high performance multispectral photodetector array for Short Wave Infrared (SWIR) imaging. The InGaAs based device uses a unique micro nano pillar structure that eliminates surface reflection to significantly increase sensitivity and the absorption spectra compared to its macro scaled thin film pixels counterpart (non pillar) We discuss the device structure and highlight fabrication of the novel high performance multispectral image sensor. We also present performance results of the device characterization showing low dark current suitable for high performance imaging applications for the most demanding security, defense, and machine vision applications.
