We present a cavity piezo-optomechanical system where microwave and optical degrees of freedom are coupled through an ultrahigh-frequency mechanical resonator. By utilizing the coherence among the three interacting modes, we demonstrate optical amplification, coherent absorption, and a more general asymmetric Fano resonance. The strong piezoelectric drive further allows access to the large-amplitude-induced optomechanical nonlinearity, with which optical transparency at higher harmonics through multiphonon scattering is demonstrated.
