TL;DR: In this paper, specific features of resonant mode conversion in nonlinear waveguides stimulated by the bi-harmonic longitudinal modulation of its parameters, including changes of the waveguide depth as well as its bending or spiraling, were studied.

TL;DR: It is shown that nonoscillating solitons may form in any of the focusing domains, even in those located close to the sample edge, in contrast to uniform thermal media, where light beams always oscillate when not launched exactly on the sample center.

TL;DR: In this paper, the existence and properties of the valley Hall edge solitons in a composite photonic graphene with a domain wall between two honeycomb lattices with broken inversion symmetry were studied.

TL;DR: In this paper, the Lugiato-Lefever equation describing the frequency comb generation in ring resonators with the localized pump and loss terms also describes the simultaneous nonlinear resonances leading to the multistability of nonlinear modes and coexisting solitons that are associated with the spectrally distinct frequency combs.

TL;DR: In this paper, a two-dimensional parity-time (PT)-symmetric structure built as a chain of waveguides, where all waveguiders except for the central one are conservative, was considered and bounded states in the continuum (BICs) whose properties vary drastically with the orientation of the line separating amplifying and absorbing domains were obtained.
