Abstract
Somebody's taking a bead on your satellite and you're blissfully unaware? Not if Spire can help it! This little group of entrepreneurs proposes a new infrared-detector sensitive to the 1.06 micron YAG-laser light used by just about everyone for target designation and ranging. Sure, GaAs photocathodes work fine for detection and imaging,but they're blind to YAG light. The answer is to use an InGaAs negative-electron-affinity transmission-mode structure lattice-matched to InP. Spire claims this combination will yield good quantum efficiency in the 0.9 to 1.6 micron range, won't require active cooling, and can be used in imaging devices. Varo Inc, a leading supplier of night-vision systems, thinks Spire is on to something; they're pitching in to test and commercialize the concept.
