Numerical analysis of mid-wavelength InSb infrared focal plane arrays

Abstract

The spectral photoresponse and crosstalk characteristic for mid-wavelength InSb infrared focal plane arrays have been numerically studied. Effects of mesa depth, substrate thickness, pixel dimension and channel length on the photoresponse and crosstalk have been investigated. Our work shows that the spectral photoresponse and crosstalk are largely dependent on the geometric design of device.
