Abstract
We investigate the relationship between the beam intensity and the four-wav e mixing diffraction efficiency of the longitudinal-field multiple-quantum- well (LMQW) photorefractive device grown at low temperature. A optimum beam intensity is found. We also explain the different mechanisms of the beam i ntensity effect on the diffraction efficiency of the LMQW device and the tr ansverse-field MQW device. Some advice on how to improve the diffraction ef ficiency is given.
