Abstract

This work demonstrates axially symmetric polarization converters based on photo-alignment in dye-doped liquid crystal (DDLC) films. A linear-shape and linearly polarized beam is applied onto a rotated homogeneous DDLC cell to achieve three axially symmetric polarizations - radial, azimuthal and vortical. Additionally, the spiral degree of the axially symmetric vortical polarization can be controlled by varying the polarization of the pumping light and the simulation results agree well with the experiment.

The measured polarization states of the probe beam emerging from the (a) homogeneous-radial cell (Fig. 2(a)), (b) homogeneous-azimuthal cell (Fig. 3(a)), and homogeneous-vortex LC cells with (c)θ = 22.5°, (d) θ = 45°,(e) θ = 67.5° (Figs. 4(a), 4(b), and 4(c)); (f) the azimuthal angle,Φ is an angle made by the line connecting the centers of the device and the probe-beam spot with the rubbing direction in the clockwise direction. The red (green triangular) dots represent the measured (theoretical) polarization states of the probe beam emerging from the samples on the Poincare sphere.
