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…
Quantum optical reset with classical memory
Evgeniy O. Kiktenko, Oleg M. Sotnikov, Ilia A. Iakovlev +5
Dynamic quantum circuits generate states that depend on the measurement results obtained during circuit execution. To date such a quantum computing model has mainly been implemente…
Observation of topological vortex solitons on disclinations
A. V. Kireev, K. Sabour, V. O. Kompanets +13
Vortex-carrying wave fields play a crucial role in photonics due to unusual propagation properties and interactions with matter, which enable numerous practical applications rangin…
Effective programming of a photonic processor with complex interferometric structure
Ilya V. Kondratyev, Kseniia N. Urusova, Artem S. Argenchiev +9
Reconfigurable photonics have rapidly become an invaluable tool for information processing. Light-based computing accelerators are promising for boosting neural network learning an…
Simulation of boson sampling with optical feedback
Yu. A. Biriukov, I. V. Dyakonov
This work presents a theoretical model of boson sampling with optical feedback, in which a subset of the interferometer's output modes is looped back into the input modes. If the b…
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…
