Abstract
We propose and demonstrate a new approach for achieving strong light-matter interactions with quantum emitters. Our approach makes use of a plasmon resonator composed of defect-free, highly crystalline silver nanowires surrounded by patterned dielectric distributed Bragg reflectors (DBRs). These resonators have an effective mode volume (Veff) two orders of magnitude below the diffraction limit and quality factor (Q) approaching 100, enabling enhancement of spontaneous emission rates by a factor exceeding 75 at the cavity resonance. We also show that these resonators can be used to convert a broadband quantum emitter to a narrowband single-photon source with color-selective emission enhancement.
