Abstract: In an asymmetric double quantum well with tunneling induced quantum interference, we designed a controllable spatial vortex four-wave mixing scheme. The spiral phase and intensity distribution of vortex four-wave mixing can be effectively controlled by tuning the detuning of the probe field and the Rabi frequency of coupling field as well as vortex field, and the numerical results can be interpreted by using the dispersion relation.
