Nano-optomechanical devices for coupling photons, phonons and spins
Cavity optomechanical devices couple light to mechanical resonator motion via radiation pressure. By fabricating cavity optomechanical devices with low mechanical and optical dissipation, combined with wavelength scale optical field confinement and resulting strong optomechanical coupling, it is possible to coherently transfer energy between photons and phonons in these systems. Diamond devices offer the additional benefit incorporating colour centre spins useful for quantum information processing. This talk will present our progress in using diamond optomechanical devices for optical information processing (memory and switching) and for spin-optomechanics.
