Abstract:A binary mixture of ferroelectric liquid crystals (FLCs) was used for the design of a channel waveguide. The FLCs possess two important functionalities: a chromophore with a high hyperpolarizability and photoreactive groups. The smectic liquid crystal is aligned in layers parallel to the glass plates in a sandwich geometry. This alignment offers several advantages, such as that moderate electric fields are sufficient to achieve a high degree of polar order. The arrangement was then… 

An azo-bridged ferroelectric liquid crystal with highly enhanced second and third harmonic generation.

A laterally azo-bridged trimer ferroelectric liquid crystal (FLC) incorporating a strong chromophore along its polar axis was synthesized and offered an innovative approach to develop new FLCs with larger NLO strength.

Ferroelectric Liquid Crystals for Nonlinear Optical Applications

NLO materials have become increasingly indispensable to today’s EO technology. Electro-optics involve these two important technologies (electronics and photonics), and the interdisciplinary field

Laterally azo-bridged h-shaped ferroelectric dimesogens for second-order nonlinear optics: ferroelectricity and second harmonic generation.

Two classes of laterally azo-bridged H-shaped ferroelectric liquid crystals (FLCs), incorporating azobenzene and disperse red 1 (DR-1) chromophores along the FLC polar axes, were synthesized and
