Guided propagation in electric-field-controlled hybrid nematic waveguides / M. Marangoni, R. Osellame, R. Ramponi, M. Buscaglia, T. Bellini. - In: JOURNAL OF APPLIED PHYSICS. - ISSN 0021-8979. - 95:11(2004), pp. 5972-5978.
Abstract:
The alignment of nematic liquid crystals in a hybrid cell can be easily reconfigured by applying an external electric field. We exploit this feature to realize a waveguiding structure whose refractive index profile can be dynamically reshaped. The mode structure of the guided light, investigated by m-lines spectroscopy at various electric field strenghts, can be well predicted by a parameter-free model based on the elastic, dielectric, and optical properties of the liquid crystal. According to such a model, the field profiles of the modes supported by hybrid nematic waveguides display very peculiar features.
