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…
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,…
Observation of condensed moire exciton polaritons in twisted photonic lattices at room temperature
Chunzi Xing, Yu Wang, Tobias Schneider +11
Moire lattices attract significant attention in double-layer graphene and TMD layer heterostructures as well as in photonic crystals due to the interesting exotic physics that emer…
