On-demand dark soliton train manipulation in a spinor polariton condensate

We theoretically demonstrate the generation of dark solitons trains in a one-dimensional exciton- polariton condensate within an experimentally trivial scheme. In particular we show that the fre- quency of the train can be finely tuned either electrically of fully optically to provide a stable and efficient output signal modulation. Taking the polarization degree of freedom into account we elucidate the possibility to additionally form on-demand half-solitons trains.
