•A cavity is applied as an actuator to improve mixing in supersonic planar mixing layer.•The coherent structures is strongly locked to frequencies from self-sustaining oscillation of supersonic cavity flow.•The normalized growth rate of cavity-actuated supersonic mixing layer is much larger than the...
