We propose a fast ground-state optomechanical cooling scheme by use of the two-mode optical cavity with a quarter-wave plate put inside. Two cavity modes are orthogonally polarized and one cavity mode dissipates to the external environment at the fast rate while the other dissipates at the slow rate. The quarter-wave plate provides linear mixing interaction between these two cavity modes. The cooling process is dominated by scattering process via the fast-decay channel, which is significantly enhanced as compared with that obtained in the resolved-sideband optomechanical cooling scheme. Meanwhile, the heating process is significantly suppressed by exploiting the destructive quantum interference between the two cavity modes with the help of quarter-wave plate.
