目前，飞秒激光微细加工在透明介质中的应用研究最广泛的可能是直写光波导法。掩埋波导、功率分路器、耦合器、光栅和光放大等器件都已经演示过了。光波导特性与样品材料特性和写入激光特性密切相关。在本文中，我们讨论了使用飞秒激光直写技术的研究人员所面临的挑战，特别强调了熔融二氧化硅和磷酸盐玻璃作为不同应用的设备宿主的适用性。
Currently, direct-write waveguide fabrication is probably the most widely studied application of femtosecond laser micromachining in transparent dielectrics. Devices such as buried waveguides, power splitters, couplers, gratings, and optical amplifiers have all been demonstrated. Waveguide properties depend critically on the sample material properties and writing laser characteristics. In this paper, we discuss the challenges facing researchers using the femtosecond laser direct-write technique with specific emphasis being placed on the suitability of fused silica and phosphate glass as device hosts for different applications.
