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 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…
