The quality factors exceed QS = 6.2×105, QB = 6.7 × 105, and QL = 1.6 × 104 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.EnglishChalcogenidesMorphologyResonatorsAll opticalIn-situ productionMicro resonatorsQuality factorsSilica fibersWide tuning rangeBottlesGlassProductionSilicaTemperatureArticle10.1364/OL.42.000907
