Abstract
Infrared detector arrays can be divided in two distinct classes: hybrid and monolithic arrays. Most hybrid infrared sensors are based on photon detectors and nearly all monolithic infrared sensors make use of thermal detectors. Hybrid detectors involve flip-chip integration of the detector and the readout integrated circuit, necessitate cooling and therefore cause substantial system overhead. Monolithic arrays do not suffer from this system overhead and most notably the resistive microbolometer thermal detectors allow ambient operating temperature. Progress in hybrid III-V based (InGaAs, InAs, InAsSb) infrared detector arrays and towards polySiGe resistive microbolometer arrays will be discussed.
