Single- and two-photon holographic recordings were performed in a photopolymer material consisting of two types of monomers: an acrylamide (1,4-bis(acryloyl)piperazine) and an epoxide ((bis(4-oxiran-2-ylmethoxy)phenyl) sulfide). Thus, cationic ring-opening polymerization and free-radical polymerization of the monomers were simultaneously initiated. The arylsulfonium salt (2-(N,N,N-triethylammonium)methyl-9-oxo-10-(4-heptyloxyphenyl)-9H-thioxanthenium dihexafluorophosphate) was chosen as the photoinitiator. Effective photopolymerization conditions were found for both (single- and two-photon) photoinitiation modes depending on the recording light intensity. The concentrations of the components (monomers and photoinitiator) in the photopolymer was optimized, and a refractive index change of as much as 0.0015 was achieved.
