Abstract
A high‐efficiency (97%) fast polarization converter (100 kHz) is
achieved using Ferroelectric Liquid Crystal (FLC). Innovatively,
by cascading FLC cells, no diffraction and residual light loss are
achieved. The flickering is less than 5%.. The contrast ratio is
1000:1. Bi‐stable focus modulation is acheived. It is a promising
candidate not just for display technologies, but also for high‐
efficiency beam‐steering applications, such as Virtual Reality
(VR)/Augmented Reality (AR), Light Ranging and Detection
(LiDAR).
