Dual-Color Mid-Infrared Quantum Cascade Photodetector in Coupled quantum well Structure

摘要：

In this paper, a novel structure for detection of two different wavelengths in midinfrared region is proposed. By attaching a capturing well to the active region, a common transportation path for electron excited by two different wavelengths is introduced. Calculated values for responsivity and detectivity in the designed Quantum Cascade Photodetector structure at 120K are: R1(λ=6.85μm)=67.5mA/W, R2(λ=12.35μm)=118.5mA/W and D1*(λ=6.85)=6.89×107J,D2*(λ=12.35)=1.2×108J,respectively.
