Quantum well intermixing is a technique developed in recent years primarily for fabricating monolithically integrated semiconductor optoelectronic devices. Intermixing can also be used to modulate nonlinear optical coefficients in semiconductor heterostructures. This has been exploited in recent demonstrations of quasi-phase-matched second harmonic generation. Here we present new results for first-order quasi-phase-matched second harmonic generation based on ion-implantation induced intermixing using the larger modulation obtained with the bulk-like /spl chi//sub zxy//sup (2)/ coefficient for which the conversion efficiency improves to such an extent that conventional photodetectors (rather than cooled CCD or photomultiplier tube) can be used to detect the second harmonic signal.
