Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 pro, 9.5 mu m and 10.8 mu m respectively. Device operation is based on inter-subband bound-to-bound transition. Asymmetry in the quantum welts is shown to give broad band responsivity spectrum at an operating bias.eninfo:eu-repo/semantics/closedAccessinfrared detectorsphotodetectorsintersubbandquantum wellsQWIPConference Object+130WOS:000257936900052N/A
