High photoresponse in room-temperature quantum cascade detectors based on a coupled-Well Design
Proceedings of SPIE, 2017Co-Authors: Tatsuo Dougakiuchi, Kazuue Fujita, Toru Hirohata, Masahiro Hitaka, Tadataka EdamuraAbstract:A high photoresponse in a room-temperature quantum cascade detector (QCD) based on a coupled quantum-Well Design is demonstrated 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 ground level. In this situation, the coupled quantum-Well QCD indicates a high responsivity of 22 mA/W as Well as a specified detectivity (D*) of 8.0×10 7 cmW -1 Hz 1/2 , both at room-temperature with commonly used 45° wedge configuration. Applying a waveguide configuration for the proposed QCD, an elevated responsivity of ~130 mA/W with a D* of 1.1×10 8 cmW -1 Hz 1/2 was obtained at room-temperature. A laser absorption spectroscopy for N 2 O gas with proposed QCD and a distributed feedback quantum cascade laser has been also demonstrated.

high photoresponse in room temperature quantum cascade detector based on coupled quantum Well Design
Applied Physics Letters, 2016Co-Authors: Tatsuo Dougakiuchi, Kazuue Fujita, Toru Hirohata, Masahiro Hitaka, Tadataka EdamuraAbstract:We report high photoresponse measured in a room temperature quantum cascade detector (QCD) based on a coupled quantum Well Design that operates with a peak response wavelength of 5.4 μm. The coupled quantum Well Design is expected to produce higher photocurrents when compared with device active regions that use a combination of simple quantum Wells. The coupled quantum Well QCD demonstrated high responsivity of 22 mA/W at room temperature with a commonly used 45° wedge-based light coupling configuration. Application of a waveguide configuration to the proposed QCD yielded an elevated responsivity of ∼130 mA/W and a specific detectivity (D*) of 1.1 × 108 cm W−1 Hz1/2 at room temperature.
