Novel photonic crystal structures with localized vibrational modes (optomechanical crystals) can be used to strongly couple a trapped light field to its mechanical degrees of freedom. Such structures are a versatile example of an optomechanical system. Recent experiments aim towards the quantum ground state of the vibrational modes. In our theoretical work, we show that entanglement between distinct vibrational modes can be achieved by intensity modulation of the driving laser.
