Analysis of silica-filled slot waveguides based on hyperbolic metamaterials

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 r...

Zusammenfassung: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.
