Generalized Modeling of Optomechanical Forces Applied to PT-Symmetric Optical Microscale Resonators

We propose an innovative optomechanical device, exploiting the force enhancement due to a quasi-PT symmetry in resonant coupled optical cavities. In order to perform the study, we develop a generalized modeling of the response theory of optical forces, including the loss and the gain effects in optical systems. The enhancement of optical force appears to be limited only by non-linearity and by the resolution of the gain/loss mechanism.
