Abstract

Liquid photopolymers produced by Polygrama-Lynx (SM-532TR and SM-532TRF) have been studied to determine their performances in terms of refractive index modulation, transparency and overall optical quality. Volume phase holographic gratings (VPHGs) based on these materials have been obtained using a 532 DPSS laser and the grating efficiency has been measured at different angles and wavelengths. Using the Kogelnik model and/or the RCWA approach, the thickness and the refractive index modulation has been determined for gratings as function of light exposure, line density, etc. Index modulations up to 0.03 together with good optical quality were obtained.
