Voltage Tunable Two-Color Quantum Well Infrared Photodetector

Abstract

Significant progress was made to further advance the quantum well infrared photodetector (QWIP) technology in two areas: 1) designating demonstrating, and understanding voltage tunable two-color QWIPs, and 2) understanding the light coupling mechanism in the so-called quantum grid infrared photodetectors. We have also been working on imprint technology to create pillars which can be used to enhance the performance of the photodetectors. The NIL molds with different period and different shape of the pillars have been created. Implementation of the small pillars to photo-detectors are in progress.
