Paper Abstract

We propose in this report an integrated optical phase modulator based on liquid crystals. It consists of an array of embedded channel polymer (ORMOCERTM) waveguides with liquid crystals serving as an active component for phase shifting. The various steps followed for the fabrication of the waveguides along with SEM and AFM scan results are presented. The pre-orientation of the liquid crystal molecules by mechanically rubbing ORMOCLAD coated layer is also shown. Finally, the results of a preliminary experiment performed to ensure the phase modulation from the modulator array geometry are presented.
