초록

We have proposed a method to calculate the absorption coefficients for the bound-to-continuum transitions in a strong biased quantum-well infrared photodetector. We have applied this method to a manufactured sample of typical device parameters, and obtained good agreements with experiments. The absorption coefficients evaluated are up to 5,700/cm at some particular operating conditions. We have also been able to make a qualitative explanation for the bias dependence of response.
