40.3: Fast Fringe‐field‐effect Free Continuous 2.25π Phase Modulation Based on Non‐linear Kerr Effect of Vertical Aligned Deformed Helix Ferroelectric Liquid Crystal

A fast (Relaxation ~25μs and response ~50μs at 55°C) high‐contrast continuous 2π phase modulation without fringe field effect (FFE) based upon Kerr effect of vertical aligned deformed helix ferroelectric liquid crystal (VADHFLC) is proposed. Specifically, FFE is a long‐term inevitable barrier for ne...

Description
Summary:A fast (Relaxation ~25μs and response ~50μs at 55°C) high‐contrast continuous 2π phase modulation without fringe field effect (FFE) based upon Kerr effect of vertical aligned deformed helix ferroelectric liquid crystal (VADHFLC) is proposed. Specifically, FFE is a long‐term inevitable barrier for nematic liquid crystal (NLC). Surprisingly, it is the 1st‐time found that no FFE exists for VADHFLC under 1μm pitch, which is an arresting feature for ultra‐high‐resolution applications. Moreover, the Kerr constant is 88nm/V2 and the contrast ratio is > 1000:1. It is a promising candidate for AR/VR, wavelength selective switch (WSS), hologram, ultra‐high‐PPI display, adaptive optics and LiDAR applications.
