Manipulation of optical near fields in vicinity of quantum sources can significantly improve various tasks, relying on radiation efficiency, polarization, directionality of extracted light, and more. Plasmonic nanostructures and their coupled ordered arrays (metamaterials) are perfect candidates for improvement of both linear and nonlinear effects, and could serve as a platform for various novel concepts. Generally, nonlinear optical phenomena are proportional to higher powers of the driving field, motivating the quest for the local electromagnetic field enhancement and electromagnetic density of states engineering.
Number of intriguing effects, emerging in nano-plasmonic environment will be discussed. Derivation of strong surface nonlinearities in metallic nano-structures will be followed by the demonstration of novel concepts of resonant second-harmonic generation in small metal particles and cascaded second-order plasmon-solitons, propagating along metal films. Plasmonic analogies of quantummechanical effects will be revised with the emphasis on the recent demonstration of plasmonic Hanle effects. Finally, the discussion of electromagnetic field quantization in the presence of dispersive and absorptive bodies will be followed by the demonstration of novel opto-mechanical effect of self-induced force, mediated by metamaterial assembly.
