Abstract
We have observed the two-wave mixing of the photorefractive GaAs/AlGaA s semiinsulating multiple quantum wells fabricated by film lift-off ap proach and proton-implanting technique. Under the non-optimized condit ion, we have obtained the two-wave mixing gain larger than 180 cm(-1) st wavelength near 784 nm for a field of 10 kV/cm. Energy transfer is also observed when the applied field is perpendicular to the grating v ector.
