Fabrication of a microresonator-fiber assembly maintaining a high-quality factor by CO2 laser welding

, 2015
We demonstrate fabrication of a microtoroid resonator of a high-quality (high-Q) factor using femtosecond laser three-dimensional (3D) micromachining. A fiber taper is reliably assembled to the microtoroid using CO2 laser welding.
