A self-consistent model for the band structure and optical gain spectra in interdiffused GaxIn1-xN0.04As0.96/GaAs single quantum wells are studied theoretically using Fick's Law and the Fermi Golden Rule. Due to quantum-well interdiffusion, the peak gain and its peak vary with the annealing time. Our results show that the interdiffusion technique can be used to tune the operation wavelength for multi-wavelength applications without degradation of device performance.
