Acousto-optic modulation in a Si-waveguide
I Ansari, D Van Thourhout, JP George… - 2021 IEEE 17th …, 2021 - ieeexplore.ieee.org
We demonstrate acousto-optic modulation (V π L~ 3.6 Vcm) in a Si waveguide circuit by
integrating a photonic compatible PZT film on the SOI chip. We then fabricated a small …

PZT based acoustic resonator for the refractive index modulation
I Ansari, J Beeckman… - 2022 Workshop on …, 2022 - ieeexplore.ieee.org
We propose a PZT based acoustic resonator to modulate the refractive index of a Silicon
waveguide. We use an inter-digital transducer (IDT) defined on the PZT film to create a …
