Low-Absorption Liquid Crystals for Infrared Beam Steering

Abstract

The objective of this project is to develop high birefringence (Delta n), large dielectric anisotropy (Delta E), and low-loss polar nematic liquid crystal compounds and mixtures for infrared applications, especially in the MWIR spectral region. The performance goals are: Delta n ~0.2 (at lambda ~4m), Delta E ~5 (at 1 kHz), and absorption coefficient alpha < 5/cm.
