Abstract :
Some recent results of spectral-characteristic investigation on integrated HgCdTe infrared two-color detector are presented. Many discussions were focused on SWIR response of the preliminary two-color detector which exhibited a sharply peaked spectrum. The reason of SWIR abnormal spectrum was rooted out, and the way to solve the problem was obtained theoretically. Finally, the proper spectral responses of two-color detector with an improved structure were accomplished as expected.
