Abstract
We calculate the spectral response of a terahertz (THz) quantum-well photodetector designed for 7Â THz detection peak frequency. We incorporate the effect of GaAs optical phonons which give rise to a strong absorption in the region of 34-36Â meV and result in an increase in reflection due to the large refractive index (n) change around this region. Comparing the calculated spectral shape with experiments, we show the improvement over the standard expressions.
