The optical properties of gold stripe waveguides enhanced with a liquid-crystal overlayer are theoretically investigated. It is shown that by proper selection of material and structural parameters extensive tunability of modal effective index, area and losses can be achieved via the electro-optic control of the nematic molecules.

Abstract
The optical properties of gold stripe waveguides enhanced with a liquid-crystal overlayer are theoretically investigated. It is shown that by proper selection of material and structural parameters extensive tunability of modal effective index, area and losses can be achieved via the electro-optic control of the nematic molecules.File in questo prodotto:
