Tunneling-induced ultraslow bright and dark solitons in quantum wells

We show the formation of tunneling-induced ultraslow bright and dark solitons in an asymmetric double-quantum- well structure based on the tunneling induced transparency. In this semiconductor structure, the pump field is replaced by the electron-tunneling coupling, which can be modulated by a stati...

Summary:We show the formation of tunneling-induced ultraslow bright and dark solitons in an asymmetric double-quantum- well structure based on the tunneling induced transparency. In this semiconductor structure, the pump field is replaced by the electron-tunneling coupling, which can be modulated by a static electric field. With appropriate conditions, we demonstrate by modulating the intensity of the static electric field that the interplay between the group velocity dispersion and the self-Kerr nonlinearity results in the generation of dark and bright solitons with ultraslow group velocity.
