Starting from first principles, we theoretically model the nonlinear temporal dynamics of gold-
based plasmonic devices resulting from the heating of their metallic components. At optical …

We suggest using tapered waveguides for compensating losses of surface plasmon-
polaritons in order to enhance nonlinear effects at the nanoscale. We study nonlinear …

Using a combination of numerical and analytical techniques we demonstrate that a metal
stripe surrounded by the active and passive dielectrics supports propagation of stable …

Optical metamaterials and metasurfaces, which emerged in the course of the last few
decades, have revolutionized our understanding of light and light–matter interaction. While …

A novel type of nonlinear symmetry breaking in symmetric plasmonic oligomers is reported.
By monitoring the strength of the second-harmonic signal while changing the polarization …

We derive general coupled-mode equations describing the nonlinear interaction of
electromagnetic modes in periodic media with loss and gain. Our approach is rigorously …

We introduce a system of two component two-dimensional (2D) complex Ginzburg–Landau
equations with spin–orbit-coupling (SOC) describing a wide-aperture microcavity laser with …

We propose a scheme to realize stable propagation of linear and nonlinear surface
polaritons (SPs) by placing a N-type four-level quantum emitters at the interface between a …

We study the interband self-induced transmission of surface plasmon polaritons in a gold
film surrounded by an external Kerr medium. We model the optical propagation by using a …

We study analytically the plasmonic modes in the graphene-coated dielectric nanowire,
based on the explicit form of nonlinear surface conductivity of graphene. The propagation …
