Abstract
We report on the photorefractive properties of thermally stable polymer composites based on the dye 2, N, N-dihexylamino-7-dicyanomethylidenyl-3,4,5,6,10-pentahydronaphthalene. At an applied field of 50 V/μm, we have achieved a dynamic range of Δn=8.5×10-3 and a net two-beam coupling gain of 202cm-1. The diffraction efficiency peaks at an applied field of 28 V/μm, giving an external diffraction efficiency of 71%.
