Spectral response of vibrational polaritons in an optomechanical cavity.

Vibrational strong coupling provides a convenient way to modify the energy of molecular vibrations and to explore the control of chemical reactivity. In this work, we theoretically report the various vibrational anharmonicities that modulate the dynamics of optomechanically coupled W(CO)-cavity. The optomechanical free-space cavity consists of movable photonic crystal membrane, which creates photonic bound states to interact with the molecular vibration.
