Effect of disorder in 3D photonic networks on their photonic band gaps

Complete photonic band gaps are frequency domains where light cannot enter a dielectric structure from any angle due to an interference-induced vanishing density of states. Band gaps can be found in binary structures with high dielectric contrast above 4. This phenomenon is well understood for periodic systems, so-called photonic crystals, but band gaps are also found in amorphous photonic networks. Here, we investigate how different types of disorder in the network’s simplices affect the photonic density of states. Using a Metropolis Monte Carlo algorithm, we generate a large population of 3D random networks with tunable statistics in the bond angle and length distribution. We calculate the photonic density of states of these random networks and correlate it to the statistical variations.
