Wave Front Shaping in Quasi-One-Dimensional Waveguides
Julian Böhm, Ulrich Kuhl
Using 10 monopole antennas reaching into a rectangular multi mode waveguide we shape the incident wave to create specific transport even after scattering events. Each antenna is at…

Waveguide photonic limiters based on topologically protected resonant modes
U. Kuhl, F. Mortessagne, E. Makri +2
We propose a concept of chiral photonic limiters utilising topologically protected localised midgap defect states in a photonic waveguide. The chiral symmetry alleviates the effect…

Dynamically encircling exceptional points in a waveguide: asymmetric mode switching from the breakdown of adiabaticity
Jörg Doppler, Alexei A. Mailybaev, Julian Böhm +7
Physical systems with loss or gain feature resonant modes that are decaying or growing exponentially with time. Whenever two such modes coalesce both in their resonant frequency an…
