Abstract

We report the experimental manipulation of liquid crystal spatial distribution in micro-scale optical waveguide via ultrashort pulse lithography. The frequency-doubled Ti:sapphire laser pulse focuses on the liquid crystal/monomer mixtures at high scanning speed, and well-defined liquid crystal/polymer triple-layer and periodic micro-waveguide is observed through phase separation and self organization mechanism.
