dc.description.abstractPhonon-photon interactions mediated by optical radiation pressure are powerful tools for quantum information transduction, for example between a quantum system used by a quantum computer or quantum memory and a quantum system used by a quantum communication network. Cavity optomechanics enhances photon-phonon interactions by co-localization of optical fields and mechanical resonances. The implementation of phononic localization in the majority of cavity optomechanical devices relies on creating suspended devices whose substrate has been selectively removed. However, this approach hinders integration with other quantum computing and communication components. As an alternative, we have developed optomechenical cavities based on a gallium phosphide-on-diamond platform with no substrate removal. This new platform takes advantage of the high speed of sound in diamond to confine phonons via total internal acoustic reflection. We have designed a device that is predicted to allow an optomechanical photon-phonon coupling rate g0~110 kHz between photons in its cavity mode and phonons in its fundamental mechanical breathing mode. Our devices also have a great potential as an optomechanical interface for coupling electron spins of defect centers in diamond crystal lattice to telecommunication wavelength photons via optomechanically induced strain.en_US
