Sol-gel holographic recording materials

Abstract

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 1 0 -2 and negligible scattering.

Effect of lanthanoid organometallic compounds on holographic storage characteristics of doped PQ/poly(hydroxyethyl methacrylate-co-methyl methacrylate) hybrids

“…Recording media have been a key issue in realizing holographic data storage. Among different materials [1][2][3][4][5], the photopolymer has been considered as a promising medium due to several advantages, such as it being easy to modify the compositions, cheap, simple fabrication and large refractive index change. Several techniques have been 4 Authors to whom any correspondence should be addressed.…”
