Zusammenfassung

Light propagation in structured photonic media covers many fascinating wave phenomena resulting from the band structure of the underlying lattice. Recently, the focus turned towards deterministic aperiodic structures exhibiting distinctive band gap properties. To experimentally study these effects, optical induction of photonic refractive index landscapes turned out to be the method of choice to fabricate these structures. In this contribution, we present a paradigm change of photonic lattice design by introducing a holographic optical induction method based on pixel-like spatially multiplexed single-site nondiffracting Bessel beams. This technique allows realizing a huge class of two-dimensional photonic structures, including deterministic aperiodic golden-angle Vogel spirals, as well as Fibonacci lattices.
