Paper Abstract

In this paper we propose new optical waveguides, made of glasses and noble metals. Such waveguides are like coaxial cables where inner metal rods are replaced by thin metal annuluses filled with a glass inside. Numerical simulations demonstrate that the proposed waveguide, having nanosize cross-section, supports propagation of modes, which phase velocity is close to the speed of light and which field is localized outside the metal. These modes are dipole-like modes and are characterized by comparatively low losses.
