“…In semiconductors charge transport can be strongly affected by electron-hole competition. Furthermore, in many of them the dependence of electron mobility on electric field intensity due to the hot electron effect can occur [6][7][8][9]. The next characteristic feature of semiconductors is connected with their electro-optical properties.…”

Temporal analysis of both the photorefractive mechanism and soliton propagation in a slab semiconductor waveguide is presented. As an example, a structure based on GaAs/AlGaAs MQWs was investigated. Both a numerical and simple analytical approach based on the bipolar band-transport model is used to derive a temporal photorefractive response on localized illumination. The corresponding propagation problem describing the evolution of screening soliton profiles in media with quadratic electro-optic effect was also discussed.
