Tailorable Integrated Photon-Phonon Interaction for Classical and Quantum Applications”

Photon-phonon interaction, as one of the strongest light matter interaction, has opened the door

to wide on-chip applications. For classical applications, the proposed research utilize photon-phonon

interaction to achieve wide-band, low insertion loss and energy saving on-chip isolator, exceeding the

state of the art performance. And for quantum applications, the proposed research couples high-Q

acoustic resonators with high-Q optical resonators by Brillouin interaction. Preliminary simulation

results show that at cryogenic temperature, we can achieve quantum cooperativity of 1 with µW

optical power. This will allow us to generate entangled photon-phonon pairs, and will have potential

applications in quantum information and computing.
