Multi-functional Infrared Sensor

Abstract

The purpose of the project is to develop plasmonic couplers and infrared detectors to realize multi-functional infrared sensors. The PI investigated in analyzing a novel detector structure for pixel-level multi-spectral infrared imaging; perforated gold films with Si3N4 overlayers, studied the fundamental understanding of surface plasmon polariton modes and their angle dependence; the effect of confinement barriers of InAs/InGaAs sub-monolayer (SML) quantum dots-in-a-well based infrared photodetectors; and characterization of multi-stack InAs/InGaAs SML quantum dots (QDs) that are grown via Stranski-Krastanov growth method. The project demonstrated the first monolithically integrated plasmonic infrared quantum dot pixelated focal plane array (FPA) to enhance the performance at specific wavelengths. The project continued to be supported to develop four different plasmonic patterns the FPA.
