Dynamic Brillouin cooling for continuous optomechanical systems

Abstract Up until now, ground state cooling using optomechanical interaction is realized in the regime where optical dissipation higher than mechanical dissipation. Here, we demonstrate that a continuous system possible by backward Brillouin scattering while exceeds which common case waveguides. The achieved an anti-Stokes process modulating intensity of coupling via pulsed pump to suppress heating processes strong regime. With such dynamic modulation, significant factor can be achieved, several orders magnitude lower for steady-state case. This modulation scheme also applied generated forward intermodal scattering.
