Multi-stability and polariton formation in microcavity polaritonic waveguides
2015, Slavcheva, Gabriela, Gorbach, Andrey V., Pimenov, Alexander, Vladimirov, Andrei G., Skryabin, Dmitry
Nonlinear polaritons in microcavity waveguides are demonstrated to exhibit multi-stable behaviour and rich dynamics, including filamentation and soliton formation. We find that the multi-stability originates from co-existense of different transverse modes of the polaritonic waveguide. Modulational stability and conditions for multi-mode polariton solitons are studied. Soliton propagation in tilted, relative to the pump momentum, waveguides is demonstrated and a critical tilt angle for the soliton propagation is found.
