Effects of Polarization Azimuth of Writing Beams on Diffraction Properties in Vector Holograms Using Radially Polarized Light

摘要

It is very important for realizing the polarization-multiplex holographic memory to clarify the optical properties of vector holograms recorded using the inhomogeneous polarized beams. In the present paper we present a simple yet useful method using the radially polarized writing beams to systematically investigate the optical properties of complicated vector holograms and preliminary data about effects of polarization azimuth of writing beams on diffraction properties. The diffraction properties of the vector holograms written in the azobenzene-containing polymers were strongly dependent on the angle between the grating vector and polarization azimuth of the writing beam. Considering the above-mentioned dependence, the theoretical calculation on the basis of Jones calculus revealed optical properties of the vector holograms written by various types of radially polarized beams.
