Abstract
Replica symmetry breaking (RSB), as a distinctive phase transition occurring between the paramagnetic and spin glass states in magnetic systems, has been anticipated and validated in diverse complex systems. Random fiber lasers with intrinsic disorder feedback have proved to exhibit diverse RSB behaviors. To date, significant attention has been mainly focused on RSB phenomena in random fiber lasers that involve only the fundamental optical mode in optical fibers. In this paper, we propose and demonstrate the RSB observation and its transient dynamics of a high-order mode (HOM) random fiber laser based on Brillouin scattering and distributed Rayleigh scattering in a few-mode fibers, for the first time, to the best of our knowledge. In this photonic system, the disorderness is not only provided by randomly distributed Rayleigh scattering and the active interplays among multiple orders of Stokes components but also by additional inter-modal couplings. Ultimately, diverse laser mode landscapes featured by unique random mode densities of the first-order Stokes emission can be aroused, accompanied by optically controlled RSB dynamics. The statistics evidentially show that Parisi’s order parameter q of the first-order HOM Stokes laser beam presents distinct distributions as per specific observation windows. Moreover, RSB dynamics in the proposed disorder system show a prominent dependence on the occurrence of multiple-order Stokes components and the mode purity of the HOM laser beams. It is believed that this approach offers new insight into exploring the underlying physical mechanisms behind the occurrence of the RSB phenomenon in photonic complex systems.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
