Nonlinear and Information Optics

Presentation

Nonlinear nanophotonics for information technologies at molecular level: NLO in quantum dots, in "nano-patterning" and "nano-imaging" (AFM, SNOM). Optical nonlinearities in metamaterials with sub-wavelength periodic and random structures - characterization and applications of enhanced and ultra-fast (fs) nonlinearities. Soliton photonics and laser wave interactions in nonlinear optical materials (wave mixing, stimulated scattering, optical phase conjugation). Properties of quantum systems in micro- and nano-cavities. Information in quantum systems.
