Spin-optomechanical cavity interfaces by deep subwavelength phonon-photon confinement
Theory of Spin-Optomechanical Coupling
A spin-optomechanical interface accomplishes two effects. First, it couples the photonic mode of a photonic crystal cavity to the phononic modes of the crystal in a pump-driven interaction. Next, it couples…
