Journal of the European Optical Society-Rapid PublicationsIn the present work, the viability of a novel recording geometry to produce reflection holographic couplers is analyzed. Recalling the idea of previous works, photopolymers are used as the recording material because they have been proven to be well ...

Optical spectroscopy of rare-earth ions doped KY(WO4)2 thin films [PDF]
, 2004 KY(WO4)2 thin films doped with Dy3+, Tb3+, Yb3+, were grown onto KY(WO4)2 substrates using liquid-phase epitaxy. Spectroscopic investigations of the grown layers were performed.

Analysis of the recording of Fibonacci lenses on photopolymers with 3-D diffusion model
Journal of the European Optical Society-Rapid PublicationsIn this work a three-dimensional diffusion model is used to model photopolymers as a recording media. This model allows us to predict the properties of the Diffractive Optical Elements (DOEs) once we recorded into the photopolymer.
