摘要
Techniques, systems, and devices are disclosed for implementing nanostructures in the optical domain that highly localize the incident electromagnetic field to with a large spectral range from the visible to the infrared range. An optical nano antenna device is provided to include a substrate; a central conductive core formed on the substrate; and a peripheral conductive shell formed on the substrate and located peripheral to the central conductive core to surround at least a part of the central conductive core. The central conductive core and peripheral conductive shell form a coaxial structure with a dimension less than an optical wavelength of light.
