The talk will briefly review previous development by the University of Hawaii / Teledyne Imaging Systems (formerly Rockwell Scientific) of MBE Hg:CdTe NIR material used in the conventional charge integration mode and selected for the Hubble Space Telescope Wide Field Camera 3 and in all three Near Infrared instruments of the James Webb Space Telescope. It will then lay out the case for x = 0.3 Hg:Cd:Te providing the perfect APD in contrast to conventional materials such as Si or InGaAs. Three immediate applications :
1) Noiseless, large format photon counting arrays for astronomy in the visible and near infrared.
2) Intensity interferometry and spectroscopy in the infrared and visible.
3) Entangled photon quantum communications.
will be used to illustrate the broad range of applications of this technology to astronomy and beyond.
