Could anyone give me the basics in the design of an optical detector using GaAs. It's for an assignment, and heres the exact wording of the question:

Consider a GaAs quantum well. Design an optical detector whose absorption begins at a photon energy of 1.46meV. For simplicity you can assume an infinite barrier energy. You will need to look up values for the band gap, effective masses, etc.
