论文摘要
沿光纤轴的纳米级有效半径变化（ERV）的表面纳米级轴向光子光子学（SNAP）微孔子可以通过将纤维内的轴向定向线插入具有飞秒激光器的轴向方向线来制造。飞秒激光铭文技术中可变参数的优化对于柔性和超高精度的ERV具有重要意义，这对于SNAP设备的性能至关重要。在这里，我们介绍了有关各种可控制造参数与SNAP微孔子引入的ERV之间关系的首次系统研究。具体而言，揭示了定性和定量处理原则。作为原则证明，通过全面优化制造参数，我们意识到了一个具有小轴向尺寸和最大ERV的特征的SNAP微孔子，这几乎是无法通过其他快速制造技术实现的。我们的工作将FS激光铭文技术推广为一种灵活而多才多艺的方法，用于以超高的精度，超低损失和高鲁棒性制造快照设备。
Surface nanoscale axial photonics (SNAP) microresonators with nanoscale effective radius variation (ERV) along optical fiber axis can be fabricated by inscribing axially oriented lines inside the fiber with a femtosecond laser. The optimization of variable parameters in the femtosecond laser inscription technique is of great significance for flexible and ultra-high precision control of ERV, which is vital to the performance of SNAP devices. Here, we present the first systematical investigation on the relationships between the various controllable fabrication parameters and the introduced ERV of the SNAP microresonators. Specifically, both the qualitative and quantitative processing principles were revealed. As a proof-of-principle, by comprehensively optimizing the fabrication parameters, we realized a SNAP microresonator with the characteristics of both small axial size and maximal ERV, which is almost impossible to realize with other SNAP fabrication techniques. Our work promotes the fs laser inscription technology to be a flexible and versatile approach for fabricating the SNAP devices with ultra-high precision, ultra-low loss and high robustness.
