Paper Abstract

A novel architecture for both QWIP heterostructure and pixel design is described. This new approach completely eliminates the dark current of a conventional GaAs/GaAlAs multiple quantum well LWIR detector. The concept is first described, then the industrial feasibility is demonstrated on a 4 X 2 array with 50 micrometer pixel pitch. The performance modeling of FPA based on this new design shows that NETD as low as 15 mK is achievable at an operating temperature of 90 K and for arrays with 30 micrometer pitch.
