title: Single-mode lasing of nanowire self-coupled resonator.
abstract: We report the observation of optically pumped lasing in self-coupled resonators constructed with dye-doped polymer nanowires. Three nanowires with a diameter of 350 nm, 360 nm and 500 nm were fabricated into different self-coupled resonators and single-mode lasing emission was obtained. The self-coupled resonators can be utilized to realize tunable laser systems and enhance the coupling efficiency of emission in ultrasmall resonators.
