Abstract
A midinfrared quantum cascade detector with a spectrally broad (deltaE/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 4.7 to 7.4 µm. The device could be operated above room temperature and showed peak responsivities of 13 mA/W at 10 K and 1.25 mA/W at room temperature. A background limited detectivity of 1.55x10(exp 10) Jones was seen up to a temperature T(ind BLIP) of 110 K.
