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

arXiv:1509.05495 · doi:10.1364/OE.23.027941

Abstract

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. Specifically, we achieve a high Q-factor of 2.12*10^6 in the microresonator-fiber assembly by optimizing the contact position between the fiber taper and the microtoroid.
