Realization of second-order photonic square-root topological insulators
Wenchao Yan, Daohong Song, Shiqi Xia +4
Square-root higher-order topological insulators (HOTIs) are recently discovered new topological phases, with intriguing topological properties inherited from a parent lattice Hamil…
Higher-order exceptional point and Landau-Zener Bloch oscillations in driven non-Hermitian photonic Lieb lattices
Shiqiang Xia, Carlo Danieli, Yingying Zhang +6
We propose a scheme to realize parity-time (PT) symmetric photonic Lieb lattices of ribbon shape and complex couplings, thereby demonstrating the higher-order exceptional point (EP…
Fractal-like photonic lattices and localized states arising from singular and nonsingular flatbands
Yuqing Xie, Limin Song, Wenchao Yan +5
We realize fractal-like photonic lattices using cw-laser-writing technique, thereby observe distinct compact localized states (CLSs) associated with different flatbands in the same…
Topological phenomena demonstrated in photorefractive photonic lattices
Shiqi Xia, Daohong Song, Nan Wang +5
Topological photonics has attracted widespread research attention in the past decade due to its fundamental interest and unique manner in controlling light propagation for advanced…
