Abstract
In my career, I have worked with several cryogenically cooled infrared detector technologies over four decades. During this period, I worked with extrinsic silicon, InGaAs, quantum well infrared photodetectors (QWIPs), quantum dot detectors, and type-II superlattice (T2SL). I am also aware of many infrared detector technologies though I haven’t directly worked on them. In last several years I was involved with managing, fabricating and delivering infrared focal planes for cameras and observational instruments. In recent years, I am involved in developing infrared cameras, multi-band, and hyperspectral instruments for Earth and planetary observational applications. In this presentation, I’ll discuss my experience as a technologist in developing novel infrared detectors/ focal plane arrays for various remote sensing applications and how T2SL focal plane array technology has changed the Infrared Landscape.
