Efficient interfacing of light and single nano-emitters: from single-photon emission to coherent nanoplasmon generation

Controlling the emission of a single nano-emitter and its coherent interaction with the nano-environment has been a topic of intensive investigation over the past decades both from the fundamental level and practical applications towards emerging quantum and nanotechnologies. In this talk, I will present our efforts in achieving ultrabright single-photon emission from a single nano-emitter and the strong coherent interaction between the emitter and an optical antenna nearby. In particular, I will talk about the combination of near-unity collection of single photon emission and ultrastrong enhancement of its emission rate with high quantum yield. I will also discuss the strong coherent back action of the nano-emitter on the optical properties of a metallic nanoatnenna and the prospect of achieving coherent nanoplasmon generation under the strong coupling limit.
