We report on the observation of an electro-optical effect for a linear rotation of the optical axis as a function of the electric field in a tilted liquid crystalline smectic phase of an achiral bent-core compound, attributed to a spontaneous helical state in its SmCSPF phase.

ABSTRACTIn the last years, in order to achieve active tuning of photonic crystals devices, the possibility to use liquid crystal inside photonic crystals has been explored.On this line of argument, in this paper, we numerically investigate a tunable T-shaped waveguide diplexer, based on a two-dimensional square lattice photonic crystal composed of silicon rods in a liquid crystals. We prove that complete splitting of the entire input wavelengths range in two sub-ranges symmetrical with respect to the middle (switching) wavelength, and propagating in right and left arms respectively, can be achieved. Moreover, changing the refractive index of liquid crystals by electro-optical effect, a tuning of switching wavelength of about 60 nm can be obtained.

Abstract:The results of a recent study of a nonlinear electro-optical effect in fullerene C60-doped nematic liquid crystal film are presented. In particular, photo-induced conduction, self diffraction effect, and permanent holographic formation in the films are explained.

Angle Of View

A liquid crystal electro-optical effect with an optically “self-compensating” director configuration is proposed to provide a device that has a wide angle of view at all gray levels. Calculations and data are presented to show the beneficial results of coupling a tunable birefringence L.C. device that has reverse pretilt alignment with a negative birefringence compensator plate.
