设计、制作并测试了一个宽光谱响应（Δ EscinE =27.3%）的中红外量子级联探测器。该探测器由26个不同设计的有源区级组成，以覆盖4.7 ~ 7.4 μm的波长范围。该器件可在室温以上工作，在10 K和室温下的峰值响应分别为13 mScinW和1.25mScinW。在TBLIP温度为110 K时，背景极限探测率为1.55×1010 Jones。
A midinfrared quantum cascade detector with a spectrally broad (ΔE∕E=27.3%) response is designed, fabricated, and tested. This detector consists of 26 differently designed active region stages in order to cover a wavelength region from 4.7to7.4μm. The device could be operated above room temperature and showed peak responsivities of 13mA∕W at 10K and 1.25mA∕W at room temperature. A background limited detectivity of 1.55×1010 Jones was seen up to a temperature TBLIP of 110K.
