在过去的几年里，渐变耦合波导阵列作为功能化光学材料的特殊代表而受到关注，其中传播光的色散和衍射可以被特定地调谐。此外，事实证明，这些系统中的光演化与粒子波函数的量子演化有根本的相似之处，因此波导阵列可以作为模拟量子力学的模型系统。最近，发展了一种新的技术，利用这种技术，可以使用飞秒激光脉冲将光波导直接写入到各种光学块体材料中，从而实现了使用其他制造方法无法实现的各种创新概念。本教程的目的是对该主题进行介绍。
Over the last few years arrays of evanescently coupled waveguides have been brought into focus as a particular representation of functionalized optical materials, in which the dispersion and diffraction of propagating light can be specifically tuned. Moreover, it turns out that the light evolution in these systems shares fundamental similarities to the quantum evolution of particle wavefunctions, so that waveguide arrays can act as a model system for emulating quantum mechanics. Recently, a novel technique was developed with which waveguides can be directly 'written' into various optical bulk materials using femtosecond laser pulses, which allows for the realization of a variety of innovative concepts which are not feasible using other fabrication methods. The aim of this tutorial is to give an introduction to this topic.
