Abstract

Inhomogeneous illumination of lithium-niobate crystals yields refractive index changes by the so-called photoreffactive effect: Electrons are excited from traps into the conduction band, the free charge carriers migrate towards the darker regions, space-charge patterns and electric fields build up, and these fields modulate the refractive index via the electro-optic effect.
