## Summary

In this study, Jakub Haberko and Frank Scheffold report on the fabrication and characterization of polymeric templates for three-dimensional disordered photonic materials. The researchers used direct laser writing in a polymer photoresist to create these templates, which were derived from hyper-uniform point patterns. To analyze the microscopic structure of the fabricated templates, electron microscopy and small angle light scattering techniques were employed. By reducing the refractive index mismatch through liquid infiltration, they achieved good agreement between the scattering data and numerical calculations based on a discrete dipole approximation. This research demonstrates the feasibility of fabricating random designer materials with isotropic photonic properties on mesoscale length scales that are technologically relevant. Furthermore, it has important implications for developing advanced photonic materials with tailored optical properties for various applications.
