Thresholdless corner vortex solitons in fractal Sierpiński topological insulators
Yiqi Zhang, Alexander V. Kireev, Victor O. Kompanets +12
Quantized vortices are ubiquitous in physics, spanning superconductivity, astrophysics, superfluid condensed matter systems, and nonlinear optics. Yet embedding vorticity into topo…
Control of eigenmode localization and coupling anisotropy by multiscan femtosecond laser writing
S. A. Zhuravitskii, N. S. Kostyuchenko, N. N. Skryabin +5
The multiscan method is widely used in femtosecond laser writing of waveguide systems to increase the refractive index contrast and to control the eigenmode shape. Here, we investi…
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 nonlinear higher-order topological insulators with unconventional boundary truncations
Changming Huang, Alexander V. Kireev, Yuxin Jiang +10
In higher-order topological insulators (HOTIs), topologically nontrivial phases are usually associated with the shift of Wannier centers to topologically nontrivial positions on th…
Observation of nonlinear topological corner states originating from different spectral charges
Victor O. Kompanets, Suge Feng, Yiqi Zhang +11
Higher-order topological insulators (HOTIs) are unique topological materials supporting edge states with the dimensionality at least by two lower than the dimensionality of the und…
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…
