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…
Vortex solitons in topological disclination lattices
Changming Huang, Ce Shang, Yaroslav V. Kartashov +1
The existence of thresholdless vortex solitons trapped at the core of disclination lattices that realize higher-order topological insulators is reported. The study demonstrates the…
Vortex solitons in large-scale waveguide arrays with adjustable discrete rotational symmetry
Yaroslav V. Kartashov
We consider vortex solitons in large-scale arrays composed of N elliptical waveguides placed on a ring, which can be fabricated using fs-laser writing technique in transparent nonl…
Two-dimensional nonlinear modes and frequency combs in bottle microresonators
Y. V. Kartashov, M. L. Gorodetsky, A. Kudlinski +1
We investigate theoretically frequency comb generation in a bottle microresonator accounting for the azimuthal and axial degrees of freedom. We first identify a discrete set of the…
