Exceptional light propagation via generalized bulk-edge correspondence
Heitor da Silva, Sergey K. Ivanov, Isaac Suárez +2
In topological photonics, the bulk-edge correspondence is conventionally imported by direct analogy with electronic systems, overlooking the fundamentally distinct spacetime symmet…
Floquet states on disclinations
K. Sabour, S. K. Ivanov, A. Ferrando +1
We show that periodic longitudinal modulation of waveguide arrays with disclination can result in the appearance of previously unexplored Floquet modes bound to the disclination co…
Observation of linear and nonlinear light trapping on topological dislocations
S. K. Ivanov, A. V. Kireev, K. Sabour +11
Topological dislocations in otherwise periodic lattices represent global structural defects that, nevertheless, typically leave the lattice periodicity intact far from the dislocat…
Observation of Light Localization at the Edges of Quasicrystal Waveguide Arrays
S. K. Ivanov, S. A. Zhuravitskii, N. S. Kostyuchenko +10
Quasicrystals are unique systems that, unlike periodic structures, lack translational symmetry but exhibit long-range order dramatically enriching the system properties. While evol…
