Analysis of silica-filled slot waveguides based on hyperbolic metamaterials

Mironov, Evgeny G.; Liu, Liming; Hattori, Haroldo T.; De La Rue, Richard M.


We have theoretically studied the optical properties of a filled slot metamaterial waveguide with lateral slab regions consisting of alternating silver–silica multilayers. It is shown that this geometry improves the subwavelength confinement of guided light and that the particular metal–dielectric ratio of 15  nm/10  nm results in substantially enhanced transmission, as compared with metal–dielectric–metal slot waveguides having similar dimensions.
