  Ground state cooling of micromechanical oscillator is a paradigmatic goal for
observing quantum mechanical effects in cavity optomechanics. We study
theoretically the ground state cooling of a mechanical oscillator in an
optomechanical cavity in presence of a quantum well placed inside the cavity.
Due to mode tailoring in presence of the quantum well, the cavity response gets
modified and leads to asymmetric heating and cooling processes. This
facilitates the cooling of the mechanical oscillator even in the
unresolved-sideband regime, via inhibition of Stokes scattering.
