英文摘要	A plasmonic-photonic hybrid system with efficient coupling of light from a fiber-coupled microspherical cavity to localized surface plasmon (LSP) modes of a gold-coated tip was proposed, which was composed of a fiber-coupled microspherical cavity and a pseudoisocyanine (PIC)-attached gold tip. To prove efficient excitation of LSP at the goldcoated tip, we experimentally demonstrated two-photon excited fluorescence from the PIC-attached gold-coated tip via a fiber-coupled microspherical cavity under a weak continuous wave excitation condition. This hybrid system could focus the incident light with coupling efficiency of around 64% into a nanoscale domain of the metal tip with an effective area of a 79-nm circle.
