These PR polymers are based on our synthesized nonlinear chromophore 4-[4-(diethylamino)-2 hydroxybenzylide-neamino] benzonitrile (Dc). For the PR devices, diffraction efficiencies as high as 90% at 25 wt.% doping level of Dc at an external applied electricfield (Eext) around 56 V/m are achieved. The reconstruction implementation is simple, of low cost, all-optical and it is capable of recovering 90%of the original images. The real-time holographic experiments were performed at Eextof just 27 V/m, which is one of the lowest reported values.Reversible holographic imaging is showed with a rise-time around 0.35 s.All Rights Reserved © 2015 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.
