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 …

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 …

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 …

The partial differential equations of Kukhtarev et al.(1977) which describe the time
dependence of hologram formation in photorefractive materials are solved analytically in the …

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

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

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 …

We present a new model (including both temperature and electron‐hole effects) of two‐
beam coupling in photorefractive semiconductors under an external dc field E 0. This model …
