Abstract

A holographic hybrid sol-gel material with excellent values of diffraction efficiency, index modulation and high photosensitivity (up to 93%, 10^-3, and 5 x 10^-3 cm²/mJ, respectively) is reported. Moroever, a high angular selectivity has been achieved $9 = 0.0967°) through the selection of the adequate nanoporous silica supporting matrix. Such a value has allowed to first demonstrate the capability of angular multiplexing in a holographic sol-gel media (up to five volume holograms with a resultant M/# of 0.83 in a preliminary approach). Shrinkage during UV curing processes has also been determined in order to evaluate how accurate can be the retrieval of the recorded data.
