RT Journal Article T1 Sol-gel holographic recording materials A1 Martínez Matos, Óscar A1 Calvo Padilla, María Luisa A1 Cheben, Pavel A1 Rodrigo Martín-Romo, José Augusto A1 Monte Muñoz de la Peña, Francisco del AB The advances in the sol-gel holographic recording materials, namely in the photopolymerizable compositions and photorefractive glasses, are reviewed. A new sol-gel holographic material is also discussed that exploits diffusion of a high-refractive-index MA:Zr complex, with the refractive index modulation of n ∼ 10^2 and negligible scattering.
