Design and simulation of resonant cavity enhanced corrugated quantum well infrared photodetectors

Design and simulation of resonant cavity enhanced corrugated quantum well infrared photodetectors

Applied Optics 45(24): 6065-6070

The dipole selection rule limits the maximum achievable efficiency in corrugated quantum well infrared photodetectors (C-QWIPs) to 50%. We consider what is believed to be a novel design that utilizes a resonant cavity enhancement technique to increase the efficiency beyond 50% by rotating the photon polarization at each pass around the cavity. Simulation results show that the quantum efficiency of this device can be enhanced up to 38% compared to that of the standard C-QWIP device.
