Abstract
SWIR imagers can operate at near room temperature with cut-off wavelengths that extended from 1.7μm (for InP lattice matched InGaAs) to beyond 2.0μm with strained InGaAs epitaxial growth on InP substrate. A leading application in the SWIR band - Night vision, requires very low dark current levels, whereas the dark current increases as the cutoff wavelength increases. We demonstrate imaging applications made possible by utilization of dark current reduction, and the physics of background and objects radiance. A newly built imager is presented.
