Applied Nanophotonics, Liquid Crystals and Biomedical Optics

Optimization of antiferroelectric liquid crystal devices at the degeneration point was discussed. The optimum viewing angular cone was obtained when the degeneracy point corresponds to 45° incidence angle and tilt angle between 0° to 45°. It was found that for the uniaxial case this angle was 41°-42° without dependence on the optical anisotropy.
