Optical vortex classification via machine learning
Tobias Schneider, Boqiang Huang, Stefan Schumacher +1
Optical vortices carry quantized phase information (topological charge) and are considered candidates for information processing in all-optical circuits. Accurately identifying the…
Skyrmions in scalar fields of non-Hermitian optical microcavities: spontaneous formation, nonlinear control, and optical forces
Jan Wingenbach, Roman Lebs, Xuekai Ma +5
Topological textures of light offer powerful routes for structuring optical fields, controlling wave transport, and manipulating matter. Skyrmions, long studied as topological soli…
Reconfigurable ultrafast perovskite polariton logic gates via nonlinear dynamics
Yuyang Zhang, Zhuoya Zhu, Xin Zeng +14
Exciton-polaritons provide a great platform for developing ultrafast all-optical logic gates for quantum and optical chips. However, progress toward practical polariton logic remai…
Universal exciton polariton logic gates in Ouroboros rings
Tobias Schneider, Stefan Schumacher, Xuekai Ma
All-optical logic gates have significantly advanced over a diverse range of photonic systems, boosted by intricate nonlinearities that facilitate the engineering of complex logic o…
Topological edge states in curved zigzag superlattices in nonlinear exciton-polaritons
Jing Wang, Tobias Schneider, Wei Hu +2
Zigzag chains allow for the formation of topological edge states. Several distinct chain architectures have been developed for this purpose. Here, we report a zigzag superlattice,…
Exceptional rings in nonlinear non-Hermitian planar optical microcavities: implementation, signal enhancement, and topology
Jan Wingenbach, Laura Ares, Xuekai Ma +4
Non-Hermitian systems hosting exceptional points (EPs) exhibit signal enhancement and unconventional mode dynamics. Going beyond isolated EPs, here we report on the existence of ex…
