Abstract
An optical microtoroid resonator including one or more nanoparticles attached to a surface of the resonator and capable of receiving an input signal from afar-field source (via free-space transmission) and outputting light propagating within the optical apparatus. A method for coupling light into and out of an optical resonator using a nanoparticle or nanoparticles to interface with spatially separated far-field optical elements.
