## Design, Fabrication and Characterization of Ordered and Disordered Photonic Materials

The second part is about reaching bandgaps with smaller wave-lengths by heat-shrinking polymer photonic hyperuniform struc-tures. Due to physical limitations, the minimum feature size reachable with the DLW set-up is limited. For some applications, smaller structures are required. We reduce the structure size by isotropically shrinking hyperuniform three-dimensional structures. By inverting them into a higher index material using atomic layer deposition and chemical vapor deposition, a band gap appears at wavelengths lower than 2$\mu$m.
