Photopolymers materials for data storage applications and diffractive elements fabrication

Abstract

The comparison between four different photopolymers is presented. The direct parameters determination as optical recording media is carried out using the zero spatial frequency limit. The bahavior of coverplated and uncoverplated material layers is analyzed. We have substituted Acrylamide monomer, carcinogenic compound, by sodium acrylate with good optical results at zero spatial frequency limit. Furthermore we have compared our PEA photopolymer (with and without crystal liquid molecules) with one commercial layer optimized for data storage applications. We have shown the potentiality of PEA to fabricate dynamic diffractive elements.
