Analysis of holographic reflection gratings recorded in polyvinyl alcohol/acrylamide photopolymer

By Helena Fernandez-Varo, Manuel Pérez Molina, Rosa Fuentes Rosillo, Manuel Ortuño, Cristian Neipp, Augusto Beléndez and Inmaculada Pascual


Holographic reflection gratings in a polyvinyl alcohol/acrylamide based photopolymer were stored using symmetrical geometry in three different thicknesses of the material. The advantage of symmetrical geometry is that exact expressions for transmittance, reflectance, and electric fields can be obtained analytically. Using these expressions, experimental data were fitted to obtain parameters such as refractive index modulation, spatial period of the grating, optical thickness or shrinkage of the material.This work was supported by the “Generalitat Valenciana” (Spain) under project PROMETEO/2011/021, ISIC/2012/013, and GV/2012/099 and by “Ministerio de Ciencia e Innovación” (Spain) under projects FIS2011-29803-C02-01 and FIS2011-29803-C02-02
