AbstractA wide tunable long-wavelength AlGaAs/GaAs quantum well intersubband photodetector is theoretically analyzed for various stages of interdiffusion. Both the absorption strength and responsivity are enhanced for certain extents of interdiffusion and the peak detection wavelength can be red shifted continuously over a large tunable range. The dark current increases with interdiffusion but is acceptable for smaller diffusion extent.
