Coupled mode analysis of polarization volume hologram

We theoretically analyze polarization holographic recording based on photoinduced dichroism and birefringence. Such vectorial recording is achieved by preferentially transforming dye molecules aligned with the incident polarization in dynamic photoanisotropic organic materials. Orthogonal linear and orthogonal circular recording geometries, which produce only pure polarization modulations, are considered. The analytic solutions of the intensity and phase of the recording beams at steady state are derived. The theoretical results indicate the dependence of diffraction efficiency on the photoinduced dichroism and birefringence and on the polarization state of the probe beam. Results of numerical simulation are provided and compared with the analytic solutions.>
