Nonlinear Physics Centre

The Nonlinear Physics Centre is engaged in the fundamental research on nonlinear phenomena and dynamics of nonlinear localised waves and solitons in different branches of physics and biophysics. The interdisciplinary research of the Group covers several topics such as nonlinear effects in bulk dielectric media and optical waveguides, all-optical technologies and switching devices, nanooptics and nanophotonics, self-trapping effects and energy transfer in condensed matter physics and biopolymers, nonlinear atom optics and matter-wave physics, including the dynamics of Bose-Einstein condensates.

More recent areas are devoted to the physics of nonlinear photonic crystals. Photonic crystals, an analog of semiconductors for light waves, are composite periodic dielectric materials that provide novel and unique ways to control many aspects of electromagnetic radiation. Harnessing the nonlinear properties of photonic crystals and photonic-crystal waveguides offers an opportunity to create the all-optical analogs of diodes and transistors that will one day enable the first all-optical computer to be built.
