Abstract
A tunable periodic guiding structure for wavelength division multiplexing (WDM) systems is proposed. It uses a liquid-crystal based substrate in a periodic dielectric waveguide. The guiding laser is implanted on a substrate formed with the liquid crystal suitability oriented. When an electric field is applied to the substrate, a tilt of the optic axis and an extraordinary index of refraction can be induced through the electro-optic effect. This structure is modelled using the model of index ellipsoid and the coupled-mode theory. It performance is evaluated for both the non-twisted nematic phase and the smectic A phase, by taking into consideration some usual technology constraints.
