Disordered optical substrates play a key role in photonic applications. Furthermore, structures of correlated, in particular hyperuniform, disorder are an emerging new class of photonic material enabling new ways of k‐space engineering. Yet, there are little to no feasible technologies that allow fabrication of tailored disordered structures to facilitate a tailored optical response. This work reports on a scalable method to fabricate substrates of tailored correlated disorder by self‐stabilized colloid deposition. Easy‐to‐access experimental parameters allow to tune lateral and vertical statistics of the disordered patterns. In addition, a model is presented that allows accurate prediction of mono‐ as well as polydisperse particle patterns. Correlation of disorder of the prepared patterns is investigated by means of the structure factor and optical measurements.

用于光子应用的量身定制的紊乱近乎均匀的基板的制造

无序的光学基板在光子应用中起着关键作用。此外，相关的，特别是超均匀无序的结构是新兴的一类新型光子材料，它可以实现新的k方式。太空工程。然而，几乎没有可行的技术允许制造定制的无序结构以促进定制的光学响应。这项工作报告了一种可扩展的方法，可通过自稳定的胶体沉积来制造定制的相关疾病的底物。易于访问的实验参数可以调整无序模式的横向和纵向统计量。此外，还提供了一个模型，可以对单颗粒和多分散颗粒的模式进行准确的预测。通过结构因子和光学测量来研究所制备图案的无序性的相关性。
