(a) Photographs of the micromanipulation system. The yellow arrow in panel (a1) highlights the xyz-ϕ motor, while the one in panel (a2) high-lights the tapered fiber and its holder. (b) Schematic representation of the ring fabrication process. After the realization of a first rectangular pattern (panel (b1)), the fiber is rotated around its axis by an angle of 20° and another rectangular pattern is partially overlap over the previous one (panel (b2)).
