Complex Nanoscale‐Ordered Liquid Crystal Polymer Film for High Transmittance Holographic Polarizer

Abstract

A special design of a complex-ordered liquid crystal polymer film is developed into a holographic polarizer. The holographic polarizer shows over 90% transmittance, which provides a simple solution to make LEDs polarized. Furthermore, the holographic polarizer exhibits intensity and polarization maintenance properties, which could be further developed for photonics applications.

High‐Resolution and High‐Throughput Plasmonic Photopatterning of Complex Molecular Orientations in Liquid Crystals

“…As a comparison, the highest resolution in maskless photopatterning techniques that allow for arbitrary director patterns is 2 μm per pixel . It is important to point out that using interference patterns of coherent light beams can also yield very high spatial resolution in photoalignments, which provide a unique technique for certain specific set of periodic director patterns . In contrast, the plasmonic photopatterning technique offers the obvious advantage in aligning LCs in all possible periodic or nonperiodic director patterns with high resolution.…”

“…The fabrication of the polarizers with such complex pattern is challenging for common methods, such as splicing or rubbing. Photoalignment shows overwhelming advantage in patterned alignment applications, and it is capable to complete a sophisticated pattern by just one step [5,6].…”

Fast-response and high-efficiency optical switch based on dual-frequency liquid crystal polarization grating

“…To further improve the efficiency, the Pancharatnam-Berry (PB) phase can be introduced. PB phase based polarization gratings have already been demonstrated in high-efficiency diffractive optical elements [17][18][19][20]. Theoretically, the input energy could be 100% diffracted into a single order [21].…”
