Abstract

Linear arrays of 256 element indium gallium arsenide (InGaAs) detectors with 100 X 30 um pixels were mounted in multiplexer packages and tested in an optical multichannel analyser (OMA). Typical performance characteristics include dark current (-5V) of 400 picoamps and responsivities of 0.75 A/W (1.3 um) and 0.14 A/W (0.85 um). The 256 element exhibited a mean room-temperature dark current of under 400 picoamps when mounted in the OMA and a dynamic range over 11 bits (2000:1). Future applications, including room-temperature detector arrays for 2.5 um and avalanche photodiode arrays for 1.0-1.7 um, are discussed.
