We propose a PZT based acoustic resonator to
modulate the refractive index of a Silicon waveguide. We use an
inter-digital transducer (IDT) defned on the PZT flm to create
a standing acoustic wave resonance in the suspended device.
We calculate the effective index change from the acousto-optic
overlap integral and illustrate its dependency on the IDT pitch.
