Chalcogenide microresonators tailored to distinct morphologies by the shaping of glasses on silica tapers
Abstract
Production of chalcogenide (As<sub>2</sub>Se<sub>3</sub>) microresonators in sphere, loop, and bottle morphologies by the shaping of glasses at appropriate temperatures between cleaved silica tapers is reported. The quality factors exceed <i>Q<sub>S</sub> </i>= 6.2×10<sup>5</sup>, <i>Q<sub>B</sub> </i>= 6.7×10<sup>5</sup>, and <i>Q<sub>L</sub></i> = 1.6×10<sup>4</sup> for the sphere, bottle, and loop microresonators, respectively. All-optical thermally assisted tuning with a rate of 0.61 nm/mW is demonstrated for a bottle microcavity pumped via a silica taper at a wavelength of 670 nm. This technique enables practical and robust in situ production of chalcogenide microresonators thermally spliced to silica fibers in several morphologies with a wide tuning range of size.
