Topological photonic crystal fibre
Bofeng Zhu, Kevin Hean, Stephan Wong +8
Photonic crystal fibres (PCFs) are optical fibres that guide light using a modulated dielectric medium. They provide an exceptionally versatile platform for various applications, t…

Observation of non-Hermitian topological disclination states and charge fractionalization
Ruifeng Li, Rimi Banerjee, Subhaskar Mandal +8
There has been significant interest in exploring topological disclination states, which effectively probe the band topology of the host material beyond the conventional bulk-edge c…

Momentum flatband and superluminal propagation in a photonic time Moiré superlattice
Linyang Zou, Hao Hu, Haotian Wu +4
Flat bands typically describe energy bands whose energy dispersion is entirely or almost entirely degenerate. One effective method to form flat bands is by constructing Moiré supe…
