We theoretically propose a scheme of an all-optical Kerr switch in a cavity optomechanical system with a Bose–Einstein condensate. It is shown that the nonlinear Kerr response can be easily switched on or off by modulating the pump beam power. We also demonstrate that such a switch can work well under a low power of the pump beam. The scheme proposed here may have potential applications in quantum electronics and quantum information networks.
