Observation of Defect States in PT-Symmetric Optical Lattices
Alois Regensburger, Mohammad-Ali Miri, Christoph Bersch +4
We provide the first experimental demonstration of defect states in parity-time (PT) symmetric mesh-periodic potentials. Our results indicate that these localized modes can undergo…
Optical mesh lattices with PT-symmetry
Mohammad-Ali Miri, Alois Regensburger, Ulf Peschel +1
We investigate a new class of optical mesh periodic structures that are discretized in both the transverse and longitudinal directions. These networks are composed of waveguide arr…
Photon propagation in a discrete fiber network: An interplay of coherence and losses
Alois Regensburger, Christoph Bersch, Benjamin Hinrichs +4
We study light propagation in a photonic system that shows stepwise evolution in a discretized environment. It resembles a discrete-time version of photonic waveguide arrays or qua…
Zitterbewegung, Bloch Oscillations and Landau-Zener Tunneling in a Quantum Walk
Alois Regensburger, Christoph Bersch, Benjamin Hinrichs +4
We experimentally investigate a discrete time quantum walk in a system of coupled fiber loops and observe typical phenomena known from the wave propagation in periodic structures a…
