Welcome !

This is the website of the Laboratory of Nonlinear Photonics and Theoretical Physics at the Department of Physics of the University Sapienza and the Institute for Complex Systems of the National Research Council. Our program is applying paradigms from the science of complex systems to light propagation, and investigating the development of complexity and self-organization in nonlinear waves. We want to test and deepen ideas of fundamental physics by using optics and photonics, and developing experiments, high performance computing approaches, and theory.

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!
