Theory of deeply subwavelength electromagnetic structuring of semiconductors due to thermal-ionization instability
I. V. Oladyshkin, D. I. Kulshin, E. O. Smolina
We develop a theory of ionization-assisted instability that governs the reflection of intense electromagnetic pulses from a semiconductor surface. Local overheating of the material…
Data-driven model reconstruction for nonlinear wave dynamics
Ekaterina Smolina, Lev Smirnov, Daniel Leykam +2
The use of machine learning to predict wave dynamics is a topic of growing interest, but commonly-used deep learning approaches suffer from a lack of interpretability of the traine…
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…
Nonlinear signatures of Floquet band topology
Aleksandra Maluckov, Ekaterina Smolina, Daniel Leykam +3
We study how the nonlinear propagation dynamics of bulk states may be used to distinguish topological phases of slowly-driven Floquet lattices. First, we show how instabilities of…
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…
Probing band topology using modulational instability
Daniel Leykam, Ekaterina Smolina, Aleksandra Maluckov +2
We analyze the modulational instability of nonlinear Bloch waves in topological photonic lattices. In the initial phase of the instability development captured by the linear stabil…
