Characterization of optical devices based on liquid crystals embedded in porous thin films

摘要

Porous; chiral thin films; with controlled microstructure fabricated by glancing angle deposition (GLAD) exhibit unique optical properties. The observed optical activity and circular (LC) embedded in the pores of the films, leading to a new class of composite optical materials. GLAD films with chiral, or "helical", microstructure have been found to impose a chiral nematic-like molecular ordering in non-chiral nematic liquid crystals.
