The Impact

The kind of defects and their concentration have a significant impact on photorefractive phenomena taking place within the structure of semi-insulating GaAs / AlGaAs multiple quantum wells. In this paper, the impact of donor-to-acceptor concentration ratio on the grating in photorefractive two-waves mixing was examined. The formation of the space charge field for different defect concentrations as well as different external electric field intensities are analyzed.

ABSTRACTHigh-order spatial harmonics of photo-induced space-charge gratings are observed in semi-insulating photorefractive quantum wells. Two-wave mixing combined with four-wave mixing in holographic thin films can provide a versatile probe of absorption and photorefractive gratings.
