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.

摘要

我们展示了使用飞秒激光三维（3D）微加工制造高品质（高Q因子）微环谐振器的过程。使用二氧化碳激光焊接将光纤锥可靠地组装到微环上。具体而言，通过优化光纤锥与微环之间的接触位置，我们在微谐振器 - 光纤组件中实现了2.12×10⁶的高Q因子。
