Abstract

Engineering photonic systems is ideal for investigating wave phenomena and to control light in random or artificially fabricated deterministic aperiodic photonic lattices. Disorder in photonic systems fosters weak and strong light localization, known as Anderson localization and coherent backscattering, respectively, evolving from multiple scattering on randomly distributed scattering centers. On the other hand, tailored light propagation by designing distinctive band gap properties of deterministic aperiodic structures, such as golden-angle Vogel spirals, and Fibonacci lattices, is highly appealing. We present paradigm-shifting techniques for the optical realization of these functional structures and investigate light control by these engineered material modifications.
