 飞秒激光微加工在光纤上的应用Femtosecond laser micromachining on optical fiber

演讲摘要

飞秒激光在对透明介质的三维加工处理方面展现了优异的性能，特别是对玻璃材料的处理能力使其成为光纤微加工的有力工具。由于光纤通常由石英玻璃材料拉制而成，其直径仅比人类的头发略粗，因此传统的加工手段很难对光纤进行精细微加工。而采用飞秒激光微加工技术则能够克服这些难题。近年来，飞秒激光微加工技术已经广泛应用于光纤器件的制备，包括光纤光栅、微型干涉仪的制备以及众多光纤微结构的制作。本报告将讨论一些光纤的飞秒激光微加工实验中涉及的参数以及相关光纤器件的应用。

Femtosecond lasers exhibit excellent capability in performing three-dimensional processing in transparent materials, especially glass, which makes them a powerful tool for micromachining optical fibers. Optical fiber is typically made of silica glass and functions as a waveguide, which is small in dimension; only slightly larger than that of human hair. Thus, micromachining of optical fibers is difficult to achieve via conventional manufacturing methods. An efficient method to overcome the above mentioned difficulty is to use a femtosecond laser. In recent years, femtosecond laser micromachining techniques have been used in a wide range of optical fiber applications; from fiber grating inscription to interferometer fabrication and recently for optical fiber microstructure creation. This presentation will explain the experimental parameters involved in femtosecond laser micromachining of optical fibers and their applications in fabrication of optical fiber devices.
