Optomechanics of random media: towards Photonic Robots

The Brownian motion of photons in a random medium induces a Brownian motion of the medium.

Anderson localization of light enhances the optomechanical interaction.

These effects are considered in a manuscript, by Silvia Gentilini and Claudio Conti, based on massively parallel numerical solutions of the Maxwell equations for random media. The goal is designing micron-sized structured devices that are activated by light and perform a prescribed motion. Understanding the role of light scattering is pivotal in the realization of "Photonic Robots."
