Exciton-polaritons are hybrid light-matter quasiparticles. They are composite and interacting bosons which can condense dynamically in a single-particle ground state via stimulated scattering. The formation of exciton-polaritons under electrical pumping has been demonstrated in quasi two dimensional systems [1-3]. In this work, we discuss the non-linear polariton emission caused by stimulated scattering in micropillar cavities under electrical pumping [4]. We distinguish our polariton laser from a conventional cavity mediated laser by probing it in a magnetic field. While a characteristic Zeeman-splitting is present in the regime of polariton lasing [4,5], it is fully absent when the device enters the weak coupling regime.

We analyze guided modes of a metal-dielectric-metal waveguide in the presence of losses when the dielectric core possesses the Kerr nonlinear response. After the analysis of effects of dispersion and losses on the linear complex modes, we calculate and discuss the nonlinear modes presented through the dependence of the modal power on the propagation constant. We show that nonlinearities bring many novel features to the mode properties, including novel bifurcation points and novel types of guided modes, the existence of limiting values for the propagation constant, and the possibility of a power growth for some of the modes.

Propagation of the fundamental and third harmonic solitary waves in medium characterized by negative refraction index at the frequency of fundamental wave and by positive refractive index at the third harmonic frequency and simultons formation are considered. Gap soliton in a novel kind of nonlinear coupler with one channel or both channels fabricated from nonlinear medium having negative refraction index is found.

We discuss the observation of Vortex Light Bullets in Arrays of Waveguides. These are among the most complex spatiotemporal solitary waves observed in an experiment. They are characterized by a complex interplay of angular orbital momentum and nonlinear, spatiotemporal effects. We show that Vortex Light Bullets exhibit a new mode of stability and show that they are robust under realistic experimental conditions. We demonstrate that they can be excited with the help of a discrete phase plate and give proof of their existence using an ultrafast spatiotemporal cross-correlation technique and rigorous numerical analysis.

Extraordinary properties of nonlinear-optical propagation processes are investigated which involve electromagnetic or elastic waves with negative group velocity. Nanostructured materials that support such waves are described. Nonlinear-optical energy transfer between contra-propagating short pulses are investigated and prospective unique photonic devices are discussed.

Plasmonic resonators are nanosized metallic antennas that convert electromagnetic waves at optical frequencies into localized fields, providing an effective route to couple photons in and out of nanoscale volumes. This unique ability makes these nanostructures excellent tools to study and manipulate light-matter interaction at the nanoscale. The strong coupling of a plasmonic resonator to light, resulting in optical cross-sections of more than 10 times the particle's physical size, is driven by collective oscillations of the conduction electrons in the metal - the so-called surface plasmon resonances.

We report on the experimental and theoretical investigation of nonlinear transformations of higher-order spatial solitons in nematic liquid crystals. We demonstrate the power-dependent conversion of a quadrupole Hermite-Gaussian mode into a single-ring Laguerre-Gaussian modal beam. We show that anisotropy induced by the boundary conditions of nematic cell strongly affects the conversion induced by nonlinear dynamics in nematic with nonlocal reorientational optical response.

We report on the problem of light propagation in tunnel-coupled waveguides. The theory of switching and forming of localized and delocalized waves in the annular system of coupled waveguides was developed. We first studied the localization of waves in nonlinear defective waveguide. It was shown that the degree of localization increases with increasing nonlinearity coefficient or intensity of input emission in defective waveguide. An effect of defective waveguide screening from neighboring zero-defect waveguides was found. Conditions for excitation of the rotatory switching in coupled waveguides with linear defect were found.

We obtain theoretically the phonon-polariton spectrum in nonlinear dielectric medium with the third order Kerr-type nonlinearity and demonstrate that the appearance of new branches located in the polariton spectrum gaps. The modulation instability of new spectrum branch waves leads to the appearance of the cnoidal waves or solitons. We theoretically investigate the properties of vector and scalar phonon-polariton cnoidal waves and spatial solitons propagating in boundless dielectric medium.
