We investigate the properties of the optical output fields from a cavity\noptomechanical system, where the cavity is driven by a strong coupling and a\nweak probe optical fields and the mechanical resonator is driven by a coherent\nmechanical pump. When the frequency of the mechanical pump matches the\nfrequency difference between the coupling and probe optical fields, due to the\ninterference between the different optical components at the same frequency, we\ndemonstrate that the large positive or negative group delay of the output field\nat the frequency of probe field can be achieved and tuned by adjusting the\nphase and amplitude of the mechanical driving field. Moreover, the strength of\nthe output field at the frequency of optical four-wave-mixing (FWM) field also\ncan be controlled (enhanced and suppressed) by tuning the phase and amplitude\nof the mechanical pump. We show that the power of the output field at the\nfrequency of the optical FWM field can be suppressed to zero or enhanced so\nmuch that it can be comparable with and even larger than the power of the input\nprobe optical field.\n
