Possibility for photorefractive effects in organic electrooptic crystals

Not Accessible

Your library or personal account may give you access

Abstract

Many electrooptic materials exhibit the photorefractive effect in which nonuniform illumination produces a spatial variation of refractive index by the following general mechanism: (1) the incident illumination produces a nonuniform space charge by the processes of photoionization, transport, and trapping; (2) the trapped charge leads to a nonuniform internal electric field by Poisson’s equation, and finally (3) the varying electric field produces a modulation of the refractive index through the linear electrooptic effect.
