TL;DR: Modulational instability can lead to the formation of regular periodic or quasiperiodic modulations of the polarization and it is revealed that such nonlinear nanoparticle arrays can support long-lived standing and moving oscillating nonlinear localized modes--plasmon oscillons.

TL;DR: This work proposes and demonstrates experimentally active nanophotonic topological cavities incorporating III–V semiconductor quantum wells as a gain medium in the structure and shows room-temperature lasing with a narrow spectrum, high coherence, and threshold behaviour, a step towards topologically controlled ultrasmall light sources with nontrivial radiation characteristics.

TL;DR: Spatial optical solitons in a one-dimensional nonlinear photonic crystal created by an array of thin-film nonlinear waveguides, the so-called Dirac-comb nonlinear lattice are studied.

TL;DR: In this paper, a new type of nonlinear metamaterials exhibiting a resonant electric response at microwave frequencies was proposed and designed, which is able to shift the frequency of the electric mode stop band by changing the incident power without affecting the magnetic response.

TL;DR: This Letter aims to present the families of two-parameter solitary waves for both (1 1 1) and (2 11) dimensional cases and to analyze their stability, and derive a novel type of analytical stability criterion for solitary waves with more than one internal parameter.
