2D polariton-solitons in semiconductor microcavities

The aim of this contribution is the theoretical analysis of 2D-localized states, or 2D polariton-solitons (PSs) in a semiconductor microcavity, operating in the strong coupling regime. The mean-field model for coherent excitons strongly coupled to the cavity photons. The lower branch of the dispersion relation of semiconductor microcavities, operating in the strong-coupling regime, contains portion with both positive and negative curvature along one spatial direction. Therefore we used the spatial modulation of the detuning to trap waves in another transverse dimension (y) forcing the PSs to move along a predefined path. These solitons consisting of both a photon and an exciton component are promising candidates for all-optical signal processing applications.
