Abstract
An optical device includes a near field transducer; and a dielectric resonant structure coupled to the near field transducer; wherein the dielectric resonant structure comprises a dielectric material that decreases a dissipation of energy in the dielectric resonant structure, relative to other dissipations of energy associated with other materials; and wherein the decrease in the dissipation of energy increases an efficiency of energy transfer from the near field transducer to a target structure, relative to other efficiencies of energy transfer from the near field transducer to the target structure.
