Abstract
We demonstrate a hybrid laser consisting of zinc oxide (ZnO) nanowires attached to the waist of a silica biconical fiber, which is pumped by 355 nm wavelength laser pulses. The laser threshold is lower than 0.1 μJ/pulse. The full-width at half-maximum (FWHM) of the cavity mode is about 0.7 nm, indicating a quality factor of about 560. The design offers convenient, efficient and compact approach to both pumping and collection of the semiconductor nanowire lasers, which represents a significant step toward high-density integration of functional building blocks for an ultracompact nanophotonic circuit.
