摘要：
A plasmonic optical device is provided operating in near ultra violet (UV) and visible wavelengths of light. The optical device is made from a substrate and nanoparticles. The nanoparticles have a core with a negative real value relative permittivity of absolute value greater than 10 in a first range of wavelengths including near UV and visible wavelengths of light, and a shell with an imaginary relative permittivity of less than 5 in the first range of wavelengths. A dielectric overlies the substrate, and is embedded with the nanoparticles. If the substrate is reflective, a reflective optical filter is formed. If the substrate is transparent, the filter is transmissive. In one aspect, the dielectric is a tunable medium (e.g., liquid crystal) having an index of refraction responsive to an electric field. The tunable medium is interposed between a first electrode and a second electrode.
