Abstract
A polarization-independent phase modulator using two thin homogeneously stratified but orthogonally oriented liquid crystal (LC) gels is demonstrated. In addition to polarization independence and submillisecond response time, the LC gel possesses a much larger phase change and lower operating voltage than the nanosized polymer-dispersed liquid crystal. For a 16 mu m transmissive E48 LC gel, the phase shift exceeds 1 pi at lambda=633 nm with an electric field strength of similar to 11 V-rms/mu m. Potential applications of such a phase modulator for laser beam steering, microlens array, and switchable two- and three-dimensional LC displays are foreseeable.
