Fig. 4: Map of the replica-symmetric (RS)-to- replica symmetry breaking (RSB) phase transition.

a The loci \(q=\left|{q}_{\max }\right|\) of points of maximum \(P\left(q\right)\) against pump power, showing distinct photonic phases with RS or RSB regimes. b, c Autocorrelation traces (AC) in the stable mode-locking (SML) and pulsating mode-locking (PML) phases for 55 and 70 mW, respectively. In Fig. 4 a, dark-green regions denote SML regimes (single-pulse and multiple-pulses), whereas light-green regions denote PML regimes (single-pulse and multiple-pulses).
