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."

Now published in Phys. Rev. A

The thinnest beam ever! In Nature Photonics

In a paper published in Nature Photonics, E. Del Re, F. Di Mei, J. Parravicini, G. Parravicini, A. J. Agranat, and C. Conti report on the observation of a sub-wavelength spatial solitons propagating in a nano-disordered ferroelectric.

The beam has transverse size of the order of 200nm with wavelength 632nm, and turns out to be the thinnest beam ever observed with a variety of applications!
