Abstract
The physics behind nonlinear propagation of picosecond pulses in micro- and nano-wire single mode waveguides either grown by chemical vapor deposition or etched into semiconductor microresonators are reviewed. If operated in the strong coupling regime exciton-polaritons form in those wires and a highly nonlinear platform is established interfacing optical, condensed matter, quantum, and statistical physics. A theory of the exciton-polariton pulse compression, pulse breaking, and emission of the backward Cherenkov radiation have been developed. This highly nonlinear dynamics is associated with the relaxation of the exciton-polariton spectrum down to low momenta, mediated solely by the exciton–exciton scattering. Such nonlinearity-enhanced thermalization results in a phase transition from propagating exciton-polariton pulses toward the formation of a non-equilibrium polariton condensate in the microwire system.
