A synergistic approach to optical modeling of PCSELs through rigorous methods and the coupled-wave theory
Arstan Bisianov, Andreas Waag
A wide range of numerical and semi-analytical approaches has been developed for optical modeling of photonic-crystal surface-emitting lasers (PCSELs). However, a systematic framewo…
Topological Floquet interface states in optical fibre loops
Arstan Bisianov, Andre Muniz, Ulf Peschel +1
We experimentally observe a coexisting pair of topological anomalous Floquet interface states in a (1+1)-dimensional Discrete Photon Walk. We explicitly verify the robustness of th…
Collapse on the line -- how synthetic dimensions influence nonlinear effects
Andre L. M. Muniz, Martin Wimmer, Arstan Bisianov +2
Power induced wave collapse is one of the most fascinating phenomena in optics as it provides extremely high intensities, thus stimulating a range of nonlinear processes. For low p…
2D Solitons in PT-symmetric photonic lattices
André L. M. Muniz, Martin Wimmer, Arstan Bisianov +4
Parity-time (PT) symmetry has attracted a lot of attention since the concept of pseudo-Hermitian dynamics of open quantum systems was first demonstrated two decades ago. Contrary t…
