Abstract

Cooling a mechanical oscillator to its quantum ground state by overcoming the effects of thermal environment has always attracted great interests [4,5]. However, the large mechanical loss, which exceeds optical loss, limits the optomechanical continuum cooling. For general backward Brillouin scattering with higher frequency and thus lower Q-factor, it was thought that it is impractical for ground-state cooling in continuous optomechanical systems.
