As one of the postgrowth band gap engineering technique, proton implantation induced quantum well intermixing has been used to tune the wavelength of two different optoelectonic devices, the quantum well laser and quantum well infrared photodetector. Large wavelength shifts have been obtained for both devices after implantation and rapid thermal annealing, without significant degradation of performance.
