Description
Summary:Up-conversion luminescence and C-band microsphere laser output is reported for an Er<sup>3&#x002B;</sup>-doped ZrF<sub>4</sub>-BaF<sub>2</sub>-YF<sub>3</sub>-AlF<sub>3</sub> (ZBYA) fluorozirconate glass microsphere. The microsphere was fabricated by heating a ZBYA glass filament using a CO<sub>2</sub> laser beam. The fabrication process accurately and repeatably produces microspheres of 68 &#x03BC;m diameter. The input and output laser light was coupled to the microsphere using a tapered optical fiber. The coupling position between the tapered fiber and microsphere was adjusted using a sophisticated three-dimensional translation stage. The up-conversion luminescence emission, single-mode and multi-mode laser at C-band (1530 to 1565&#x00A0;nm) were observed when pumped using a 980&#x00A0;nm laser.
