Abstract
The photorefractive response of semi-insulating multiple quantum well structure operating with an external electric field applied along the quantum well planes to a localized illumination is investigated. An approximate steady-state relation between space-charge electric field and light intensity is found. To confirm used approximations, band transport model is numerically solved. The time evolution of the space-charge field is also analyzed.
