Multicolor infrared photodetector |
摘要 |
A multicolor infrared detection device comprising a number of doped quantum well structural units. Each unit consists of a thick well and a thin well separated by a thin barrier. This arrangement produces strong coupling. Infrared radiation incident on the device gives rise to intersubband absorption. For each transition a photosignal results which allows the detection of a plurality of incident frequencies.
