High photoresponse in a room temperature quantum cascade detector (QCD) based on a coupled quantum well design is reported with a peak detection wavelength of 5.4 μm. In this design, forward electron transfer is engineered to be five times as large as relaxation back to the ground level. In this situation, the coupled quantum well QCD indicates a responsivity of 7 mA/W as well as a specified detectivity (D*) of 2.5×10^7 cmW^-1Hz^1/2, both at room temperature with commonly used 45˚ wedge configuration. Applying a waveguide configuration for the proposed QCD, an elevated responsivity of ~40 mA/W with a D* of 3.5×10^7 cmW^-1Hz^1/2 was obtained at room temperature. A laser absorption spectroscopy for N2O gas with proposed QCD and a distributed feedback quantum cascade laser has been also demonstrated. |
