optical communication, diffraction grating, analyticalmodel, absorbent photopolymer, spatial harmonics.


We present an analytical model of dynamics of (m+1) spatial harmonics of spatial grating profiles with taking into consideration both record mechanisms (polymerization and components diffusion), absorption, interference pattern contrast and optional photopolymerization nonlinearity. On the base of numerical simulation we examined an influence of these parameters on spatial along thickness of a film.
