摘要

Here we demonstrate the fabrication processes and working parameters of tunable phase retarders based on photoaligned Liquid Crystal (LCs) cells by combining the photo-pattering and self-assembly processes. The proposed LC devices were assembled by Indium Tin Oxide (ITO) transparent conductive layers deposited on a glass and quartz substrates and spin coated with thin polyamide (PI) layer as photo-alignment material. We study the voltage-transmittance and phase retardation behavior of assembled LC cells and demonstrate polarization sensitive spatial patterns,that openpromisingfeaturesfornext generation opticalelementsaswaveplates,lenses,phaseretarders,etc.
