Abstract Random Lasers (RLs) and Random Fiber Lasers (RFLs) have been the subject of
intense research since their first experimental demonstration in 1994 and 2007, respectively …

This is an extended version of my Nobel Lecture, delivered on December 8, 2021. I will
recall the genesis of the concept of multiple equilibria in natural sciences. I will then describe …

Recent developments in the field of micro and nanophotonics have shown that it is possible
to make use of the intrinsic disorder in photonic materials to create useful optical structures …

Linear multimode optical systems have enabled clean experimental observations and the
applications of numerous phenomena that continually extend the boundaries of wave …

Mode-locking is a process in which different modes of an optical resonator establish stable
synchronization through non-linear interactions. This self-organization underlies light …

Scattering of light by disordered structures is a common phenomenon in our daily life. For
many scientific applications, scattering is often treated as a detrimental effect. However …

Random lasers have been recently exploited as a photonic platform for studies of complex
systems. This cross-disciplinary approach opened up new important avenues for the …

Replica symmetry breaking (RSB), as a featured phase transition between paramagnetic
and spin glass state in magnetic systems, has been predicted and validated among random …

We report on measurements of the statistical fluctuations of the output intensity in a
continuous-wave-pumped erbium-doped one-dimensional random fiber laser (RFL), with …

The photonic analog of the paramagnetic to spin-glass phase transition in disordered
magnetic systems, signaled by the phenomenon of replica symmetry breaking, has been …
