Abstract

Photorefractive polymers offer advantages such as their considerable flexibility in synthesis, doping, processing, and low cost. Furthermore, compared to their crystalline counterparts, they offer the possibility of improved value in the photorefractive index change figure-of-merit n³-r/ϵ, owing to the small dc dielectric constant ϵ and reasonable linear electrooptic coefficient r and refractive index n.¹
