For most regimes descriptions of photorefractive behavior by electron–hole transport with a
single species of impurity levels and by electron–hole transport with two species of impurity …

Space-charge fields in photorefractive materials enhanced by moving fringes are studied for
simultaneous electron–hole transport. Two distinct models, one with a single set of impurity …

The steady‐state space‐charge field and the response time of a photorefractive material
illuminated with a sinusoidal interference pattern are derived for two models in which both …

The photorefractive band transport model is extended to include magnetic effects. The
Newtonian equation of motion for electrons in the conduction band under combined electric …

The time evolution of space-charge field gratings in photorefractive media is derived for a
simple two-level electron–hole-transport model. At one level, charge transfer occurs by …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

A two-center photorefractive model permitting all center-to-band transitions and electron-
hole charge transport unifies several models describing subsets of these transitions. Using …

A model of the photorefractive effect is presented that includes a shallow-trap level (hole or
electron trap) as well as a species of deep traps with electron and hole excitation. It is shown …

Light-induced charge transport processes are essential for photorefractive effects in
electrooptic crystals. Charge driving forces, charge transport models and experimental …

The band transport model describes charge statics and dynamics within photorefractive
materials. Here a steady-state solution is found for the setting in which an arbitrary optical …
