Abstract
A holographic photopolymer based on SU-8 epoxy resin as the binder and trimethylolpropane ethoxylate triacrylate as the monomer with an iodonium salt photoinitiator was studied. A diffraction efficiency of 93% and a refractive index modulation of were obtained from a thick sample with write beam intensities of at a wavelength of , an exposure time of , and a postbaking at for . The material exhibits good heat resistance in the range from to and long projected life.
