PLASMONIC AND PHOTONIC RESONATOR STRUCTURES AND METHODS FOR LARGE ELECTROMAGNETIC FIELD ENHANCEMENTS

摘要

Devices for producing localized surface plasmon resonances are described having a plasmonic resonator and a photonic structure electromagnetically coupled to the plasmonic resonator. The device can include a hybrid photonic plasmonic resonator that contains plasmonic and photonic resonators, and are optionally coupled to a photonic waveguide, or a plasmonic resonator coupled directly to a photonic waveguide. The plasmonic resonator can be one or more nanoparticles. The devices can produce substantial increases in coupling efficiencies and sensitivity for use in several applications, including SERS and refractive index sensing.
