Abstract
The world's first 2048 X 2048 HgCdTe infrared focal plane array (FPA) has been developed by Rockwell Science Center for infrared astronomy. The Hawaii-2 is the largest CMOS multiplexer designed to date, developed to interface with both infrared and visible detector arrays. The 18 micrometer pixel pitch was selected to accommodate both reasonable telescope optics and maximize yield in the fabrication of such a large readout. The fabrication uses world-class submicron photolithography to maximize yield of high quality devices. We will report on the characterization of FPAs using the Hawaii-2 multiplexer mated to SWIR detector arrays with a spectral response of 0.9 micrometer to 2.5 micrometer. These detector arrays have been processed on Liquid Phase Epitaxy (LPE) HgCdTe on sapphire substrates, also known as PACE-1. We also report on characterization of Silicon detectors in terms of their quantum efficiency, spectral response, and dark current.
