Abstract

In recent years, a worldwide growing demand for Short-Wave Infrared (SWIR) imaging has increased dramatically. The requirement for such imagers span military, space and commercial applications. The ideal SWIR detector realizes low power, small size, and low noise, capable of imaging under a wide range of illuminations from daylight to starlight, with on-die advanced imaging capabilities, such as high dynamic range (HDR) and active imaging. In this paper we present a new 640x512/15μm InGaAs focal plane array (FPA) specifically developed for low noise (LN) applications. The detector temperature is stabilized by a thermoelectrical cooler (TEC) typically at 20 C demonstrating extremely low dark current with excellent imaging under low light level (LLL) conditions. The detector's read out noise was measured to be lower than 15e- with correlated double sampling. We demonstrate the ROICs active imaging applications at sub μs gates and elaborate on the overall electro-optical performance.
