Abstract

Integrated optic devices using liquid crystals embedded in optical waveguiding structures have advantages in terms of compactness and high performance. Such devices exploits the high electro-optic effect and the good optical properties of liquid crystals, in particular their high birefringence and their low absorption, combined with low loss optical waveguides. Optical switches based on ion-exchanged channel glass waveguides and liquid crystals operating in the C-band used for optical communications have been designed by using beam propagation method. Polarization independent configurations are described and evaluated in terms of crosstalk and losses. Feasibility of tunable optical filters using composites materials made of polymer and nematic liquid crystals to be used in optical communication and sensor systems is demonstrated. Materials and fabrication procedures of both integrated optical switches and filters are also discussed.
