Abstract

Two-beam coupling (TBC) in a photorefractive polymer using transmission and reflection geometries is investigated. With drift (due to an applied electric field) and diffusion, a linearized analysis suggests a phase shift between the intensity grating and the induced refractive index grating different from the ideal value of 90 degrees, which is supported by experimental results using a transmission grating geometry. In a self-pumped reflection grating geometry, which is also experimentally studied, the phase shift can be closer to 90 degrees due to a shorter grating period. Absorption and absorption gratings during TBC is also experimentally investigated.
