Monolithic photorefractive organic glasses with large coupling gain and strong beam fanning
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 mum thick.
