摘要：

We discuss the device physics and detector performance of quantum well infrared photodetectors (QWIPS). On the basis of these results, large two-dimensional arrays of 128 x 128 pixels were fabricated and measured. The excellent long-wavelength imaging results (99 % of the pixels working and a noise-equivalent temperature difference NE-DELTA-T = 10 mK) demonstrate the potential of this new GaAs QWIP technology.
