摘要：
We introduce here a novel light coupling scheme for quantum well infrared photodetectors (QWIPs). The new device structure utilizing this coupling scheme, referred to as the corrugated QWIP (C-QWIP), couples normal incident light effectively even for detector size as small as 50 x 50 mu m(2) and shows little spectrum narrowing effect, indicating that it can be applied to the manufacturing of high resolution focal plane arrays and is a viable candidate for multi-color or broadband infrared detection.
