我们提出了初步的结果，直接观察的签名的本地化光在超快激光刻写（ULI）无序晶格，其中包含一个阵列的倏逝耦合，一维光波导在玻璃中的折射率引入一定量的无序。数值模拟进行了初步的实验设计的可行性进行了测试。这种可配置的ULI无序波导晶格应该打开一个平台，研究光的横向局域化现象及其统计性质。
We present initial results of the direct observation of the signature of localized light in an ultrafast laser-inscribed (ULI) disordered lattice that contains an array of evanescently coupled, one-dimensional optical waveguides in glass in which certain amount of disorder in refractive index was introduced. Numerical simulations were carried out to test the feasibility of the initial experimental design. Such configurable ULI disordered waveguide lattices should open up a platform for investigating the phenomenon of transverse localization of light and its statistical nature.
