%X We demonstrate a silver nanowire ring resonator with a ring diameter of 10.2 ¦Ìm. The ring cavity is formed by coupling both ends of a 145-nm-diameter single silver nanowire into a closed loop. A Q-factor of 160 and a free spectral range of 10.6 nm are obtained for light centered around 800 nm. The self-coupled ring structure offers opportunities for realizing compact plasmonic resonators with tight confinement for hybrid optical and plasmonic signal processing.
