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 gap solitons and truncated nonlinear Bloch waves in temporal lattices
Christoph Bersch, Georgy Onishchukov, Ulf Peschel
We experimentally demonstrate the formation and stable propagation of various types of discrete temporal solitons in an optical fiber system. Pulses interacting with a time-periodi…
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…
