Title:
Spontaneous parametric down-conversion induced by optomechanical gradient forcesin nanophotonic waveguides 
Abstract:
Optomechanical gradient forces arise from evanescent fields of guided waves in parallel photonic waveguides. When designed to be of an attractive nature, they increase exponentially as the gap between the waveguides decreases. Moreover, the amplitude of the gradient force can be well controlled due to its linear dependence on the input laser power. Here, we propose to exploit the intrinsic nonlinear nature of the optomechanical gradient force to induce a tunable three-wave coupling between the f...    »
