Abstract
In this work is we have developed the analytical models of holographic formation of polarization grating in polymerdispersed liquid crystals (PSLCs) by non-uniform recording field and its subsequent readout by uniform plane optical wave. The formation model is based on Jones formalism for recording field description and on equations of photoinduced Fredericks transition for description of dielectric tensor perturbations. The model of gratings readout is based on the system of coupled-wave equations solutions in the fixed-field approximation. Photo-induced absorption coefficient changing and the strong surface adhesion effects are taken into account. According to the obtained relations, numerical simulation of the spatial changing of the dielectric tensor was made for some forms of amplitude and phase non-uniformity of recording beams. For each complex of formation conditions the diffraction characteristics are also investigated numerically. The influence of recording field non-uniformity on grating’s diffraction characteristics is shown.
