  • Abstract
    In this paper, a novel structure for detection of two different wavelengths in mid-infrared 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)=67.5 mA/W, R2(λ=12.35µm)=118.5mA/W and D*1 (λ=6.85)=6.89×107J, D*2 (λ=12.35)=1.2×108J, respectively.
