Abstract
The change in the second-order nonlinear susceptibility of an asymmetr ic quantum well (AQW) superlattice induced by ion beam-enhanced interm ixing has been measured. The surface-emitted second-harmonic intensiti es radiated from implanted and masked areas of an AQW waveguide were m easured and compared for incident wavelengths between lambda=1480 and 1600 nm. Intermixing resulted in a 60 meV blueshift of the AQW band ed ge and a uniform suppression of the AQW second-order susceptibility, w hile the masked AQWs were unchanged.
