Device fabrication. (a) Scanning electron microscope (SEM) image of diamond micro-waveguides. (b) SEM image of a functionalized tapered fiber, in contact with a diamond micro-waveguide. (c) Optical image of assembled device. (d) Confocal scans of fluorescence detected from two fiber ends (shown in top and bottom panel). The micro-waveguide is optically pumped with a green (532 nm) laser excitation source. Light originating from a single NV center is shown in the dotted circles.
