(Optical Society of America, 2002-04-01)Diffusion-based models of grating formation in photopolymers have been proposed in which the rate of monomer polymerization (removal) is directly proportional to the illuminating intensity inside the medium. However, based ...
-
(Optical Society of America, 2003-08-11)Some of the theoretical models in the literature describing the mechanism of hologram formation in photopolymer materials predict the existence of higher harmonics in the Fourier expansion of the recorded refractive ...

(Optical Society of America, 2002-02-01)The one-dimensional diffusion equation governing holographic grating formation in photopolymers, which includes both nonlocal material response and generalized dependence of the rate of polymerization on the illuminating ...
-
(Optical Society of America, 1993-08-01)Artificial index gratings, which are composed of binary microstructures of sizes less than the incident wavelength, are analyzed as functions of the filling factor or duty cycle of the microstructures. Different models for ...

Monomer diffusion rates in photopolymer material. Part I. Low spatial frequency holographic gratings (Optical Society of America, 2011-03-01)For photopolymers, knowing the rate of diffusion of the active monomer is important when modeling the material evolution during recording in order to understand and optimize their performance. Unfortunately, a confusingly ...
