Nanoscale Quantum Confined Structures with Photon Controlling Cavities

Abstract

The objective of the grant was to investigate novel quantum confined heterostructure coupled with photon controlling cavities. These would be used for developing high operating temperature (HOT) mid wave infrared (MWIR, 3 5 microns) and long wave infrared (LWIR) sensors. The heterostructures would be based on nanoscale self assembled quantum dots in a well design (DWELL). This effort will include a trade study to evaluate these technologies and a rigorous investigation of the performance parameters of these technologies. The final objective of this effort would be to demonstrate a 320 x256 MWIR focal plane array (FPA) operating at higher temperatures. There was a significant effort on developing quantum dot based focal plane arrays with plasmonic resonators. Promising results were obtained on plasmonic enhancement in 320x256 focal plane arrays.
