Abstract

Infrared detector applications often require detector sensitive areas that are as closely spaced as possible. In particular, imaging systems often need close-packed detectors in order to increase their resolution. The imaging/resolution performance of two-dimensional arrays may be limited by the fact that the electron-hole pairs created by an optical disturbance (detection) may diffuse long distances from where the electron-hole pair was created. Some results of measurements of crosstalk and out-of-field signals in InSb detectors specially fabricated for these measurements are given herein. The detector arrays were configured in a manner such that the measurements would allow differentiation between electrical and optical (carrier diffusion) crosstalk.
