Noise-assisted routing in mode-coupling devices

Abstract

The dynamical control of energy transfer between interacting systems is fundamental in diverse applications related to physical, electronic and chemical processes. Recent developments show that noise may enhance or suppress power transfer in systems described by Coupled-Mode Theory. We show a semi-analytic approach to utilize dynamical noise to produce routing in coupled mode devices. We present results for an optical mode-coupling device with induced noise in the refractive index of the material. However, our approach is valid for networks of coupled oscillators of any type as long as their dynamics are described by Coupled-Mode Theory.
