Abstract

A fiber-based device with a novel nematic liquid-crystal overlay compatible with silica fiber at room temperature is reported here to demonstrate polarization-independent modulation. The device is formed using a polished half-coupler block that has been surface treated so that the liquid crystal affects orthogonal polarizations in a similar and simultaneous manner. This permits the modulation of input light of arbitrary polarization on the application of an electric field.
