Monolithic Photorefractive Organic Glasses with Large Coupling Gain and Strong Beam Fanning

Abstract

A monolithic photorefractive organic glass with large gain coefficients at low electric fields is presented. The molecule DCDHF-6 (see Figure) acts simultaneously as charge transport material and nonlinear optical chromophore. Strong beam fanning is observed with suppression of the initial beam to 25 % of its initial value in samples only 100 μm thick.
