Identifying topology of leaky photonic lattices with machine learning
Ekaterina O. Smolina, Lev A. Smirnov, Daniel Leykam +2
We show how machine learning techniques can be applied for the classification of topological phases in leaky photonic lattices using limited measurement data. We propose an approac…
Self-steepening-induced stabilization of nonlinear edge waves at photonic valley-Hall interfaces
Ekaterina O. Smolina, Lev A. Smirnov, Daniel Leykam +1
Localized nonlinear modes at valley-Hall interfaces in staggered photonic graphene can be described in the long-wavelength limit by a nonlinear Dirac-like model including spatial d…
Gradient catastrophe of nonlinear photonic valley-Hall edge pulses
Daria A. Smirnova, Lev A. Smirnov, Ekaterina O. Smolina +2
We derive nonlinear wave equations describing the propagation of slowly-varying wavepackets formed by topological valley-Hall edge states. We show that edge pulses break up even in…
Nontrivial coupling of light into a defect: the interplay of nonlinearity and topology
Shiqi Xia, Dario Jukić, Nan Wang +9
The flourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introdu…
Topological edge states and gap solitons in the nonlinear Dirac model
Daria Smirnova, Lev Smirnov, Daniel Leykam +1
Topological photonics has emerged recently as a novel approach for realizing robust optical circuitry, and the study of nonlinear effects in topological photonics is expected to op…
Multipolar third-harmonic generation driven by optically-induced magnetic resonances
Daria A. Smirnova, Alexander B. Khanikaev, Lev A. Smirnov +1
We analyze third-harmonic generation from high-index dielectric nanoparticles and discuss the basic features and multipolar nature of the parametrically generated electromagnetic f…
Dissipative plasmon solitons in graphene nanodisk arrays
Daria A. Smirnova, Roman E. Noskov, Lev A. Smirnov +1
We study nonlinear modes in one-dimensional arrays of doped graphene nanodisks with Kerr-type nonlinear response in the presence of an external electric field. We present the theor…
