pixels linear array quantum well infrared photodetectors with 2D diffraction coupling grating have been fabricated. The gratings were etched by ion beam etching. The substrate was thinned to about 200 micrometer. For backside incidence and at 80K operation temperature, the average responsibility and detectivity were 2.75×10 4V/W and 2.52×10 9 cmHz 1/2 /W, respectively. The non uniformity of the responsibility and detectivity were 5.2% and 10.3%, respectively. Human body infrared image were captured...
