Abstract :
We demonstrate GaAs optomechanical crystals with large coupling rates (g0/2π ≈1.1MHz) through the photoelastic effect. We show a significant (≈30%) orientation dependence of g0, observe 2.5 GHz regenerative oscillations, and explore excitation via piezoelectrically-driven surface-acoustic-waves.
