Abstract

Two-dimensional (2D) gratings made up of an array of differently twisted nematic structures are obtained by crossed assembling of 1D polarization holograms recorded at the photoaligning substrates. The rotating linear polarization pattern, produced by the interference of two opposite circularly polarized beams, is recorded on the azo-dye doped polyimide aligning layers. The 2D gratings diffract light in different directions with different polarization states, that can be optically controlled. Orthogonal circularly and linearly polarized diffraction orders are simultaneously obtained irradiating the grating with a linearly polarized beam. An external ac voltage allows to completely control the diffracted energy distribution.

Experimental setup for the recording of polarization holograms on the photosensitive substrates. M – mirror, BE – beam splitter, P – polarizer, WP – quarter wave plates, S – photosensitive substrate, q – grating vector, RC – right circular polarization, LC – left circular polarization. The dashed region denotes the rotating linear polarization pattern.
