We theoretically introduce a mechanism for achieving the mechanical analog of optical Kerr nonlinearity. By exploiting optomechanical interactions in deformable waveguide structures, a nonlinear phase shift proportional to the optical field intensity is induced. Resulting Kerr coefficients several orders of magnitude larger than the intrinsic silicon optical Kerr coefficient are predicted.
