Abstract

An electrically tunable achromatic polarization rotator has been developed based on the hybrid splay-twist (HST) and hybrid-aligned super twist (HAST) liquid crystal. The continuous angular rotation, and achromatic operation across the entire visible spectrum. The tuning range of the polarization rotator is up to 90° or to 180° and the degree of linear polarization (DOLP) remains. Based on the HST-LC, the multi-functional smart glass is realized with light field, dimming and scattering control. This work provides possibilities in the design of optical systems and spatially polarization multiplexing elements. The designed smart glass provides novelties in smart (green) architecture.
