摘要
近年来, 微光学元件的制备与应用受到人们的广泛关注。微光学元件体积小、重量轻及制造成本低, 并且易于与微机电系统相集成, 能够实现普通光学元件难以实现的功能, 在光纤通信、信息处理、航空航天、生物医学、激光技术、光计算等领域, 突显出重要的应用价值。飞秒激光因其超短的脉冲宽度和超高的瞬时功率, 能够实现超高精度的微纳加工, 轻松突破衍射极限。飞秒激光加工技术对材料没有选择性, 加工过程也非常灵活, 可以进行任意复杂结构的加工, 丰富了微光学元件的制备种类。飞秒激光还能在现有结构或系统上进行集成加工, 极大扩展了微光学元件的应用。简要概述了微光学元件的优点及一些常用的制备方法, 同时对飞秒激光加工技术进行了简单概括, 对近年来飞秒激光制备各种微光学元件的实验和应用研究进行了综述, 最后对微光学元件未来的研究方向进行了预测和展望。
Abstract
Fabrication and application of micro-optical components are attracting broad attention in recent years. Micro-optical components have important applications in the fields of optical fiber communication, information, aerospace, biomedicine, laser technology, and optical computing, because they can achieve function that the ordinary optical components are hard to realize for their small size, light weight, low cost and ease to integrate with micro-electromechanical systems. Femtosecond laser can achieve micro/nano fabrication with ultra-high precision due to their ultrashort pulse width and ultrahigh pick power, which breaks the diffraction limit easily. Femtosecond laser can process almost any materials flexibly with arbitrary complex structures, which enriches the fabrication of micro-optical components. Further, the femtosecond laser processing can be carried out on the existing structure or system, which greatly expands the application of micro-optical components. A brief overview of the advantage and common fabrication methods of micro-optical components is given and the femtosecond laser processing technology briefly is summarized. Then, the experimental and applied research of micro-optical components fabricated with femtosecond laser are reviewed. Finally, some prospects and forecasts about the research of micro-optical components are given.
