The laboratory is funded by the COMPLEXLIGHT project of the European Research Council (grant number 201766, area PE2).
Our program is applying paradigms and methods from the science of complex systems to light propagation and investigating the development of complexity and self-organization in nonlinear waves.

In a manuscript published in the Physical Review A (arXiv:1305.1053), Silvia Gentilini, Neda Ghofraniha, Eugenio Del Re, and Claudio Conti review the work about the generation and experimental characterizations of shock waves in thermal lensing, including the effect of disorder.

In a paper published in Nature Communications (arXiv:1304.8002), Marco Leonetti, Claudio Conti and Cefe Lopez report on the experimental evidence and the theory of an all-optical transistor-like action in a random laser.
It is shown that a signal can be routed inside a disordered resonator by using an all-optical control gate: a specific frequency can be transported, switched and amplified in different positions of the system.
Multiple frequencies can be processed simultaneously. The results are based on a novel spatio-spectral reconstruction technique.
This is the first demonstration of a logical operation in a random laser, and also the measurement of a novel kind of controlled transport in an active random system.
The picture below (by Marco Leonetti) shows the demonstrated transistor, with the gate (G), the source (S), and the drain (D) signals indicated in analogy with an electronic field effect transistor.
