Abstract

This investigation demonstrates the feasibility of the radial and azimuthal axially symmetric LC structure using double-side photoalignment in a dye-doped liquid crystal (DDLC) cell. A linear and linearly polarized beam is applied to a rotated DDLC cell to produce an axially symmetric LC alignment. Notably, double-sided photoalignment is performed at a temperature that is maintained just above the clear point. Conformation of the axially symmetric LC devices can be controlled by varying the polarization direction of the pumping light, and the simulation results correlate well with OR closely correspond to the experimental results.
