 飛秒激光微加工在光纖上的應(yīng)用Femtosecond laser micromachining on optical fiber

演講摘要

飛秒激光在對(duì)透明介質(zhì)的三維加工處理方面展現(xiàn)了優(yōu)異的性能，特別是對(duì)玻璃材料的處理能力使其成為光纖微加工的有力工具。由于光纖通常由石英玻璃材料拉制而成，其直徑僅比人類的頭發(fā)略粗，因此傳統(tǒng)的加工手段很難對(duì)光纖進(jìn)行精細(xì)微加工。而采用飛秒激光微加工技術(shù)則能夠克服這些難題。近年來(lái)，飛秒激光微加工技術(shù)已經(jīng)廣泛應(yīng)用于光纖器件的制備，包括光纖光柵、微型干涉儀的制備以及眾多光纖微結(jié)構(gòu)的制作。本報(bào)告將討論一些光纖的飛秒激光微加工實(shí)驗(yàn)中涉及的參數(shù)以及相關(guān)光纖器件的應(yīng)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.
