Simulation of nonlinear polariton dynamics in microcavity wires for polaritonic integrated circuits

We have developed a model of the nonlinear polariton dynamics in realistic strongly-coupled 3D non-planar microcavity wires based on driven-disspative mean-field Gross-Pitaevskii equations. We find that the typical microcavity nonlinear optical bistability response evolves into multistability upon variation of realistic model parameters and discuss its origin in terms of multiple co-existing transverse cavity modes. Conditions for formation of self-assembled lossless multimode pulses: polariton solitons, and geometry limitations for their stable propagation are identified.
