We theoretically investigate nonlinear effects such as four-wave mixing (FWM) and bistability in a cavity electromechanical system based on the electromagnetically induced transparency effect. We show that the FWM can be resonantly enhanced under conditions of reduced linear absorption. We also demonstrate that bistable behavior of the mean intracavity photon number can appear in this system. The system may have potential applications in communication networks for frequency conversion.
