Fig. 6: The soliton dynamics of period-doubling bifurcation.
From: Multi-port real-time observation for ultrafast intracavitary evolution dynamics
a The real-time evolution process (above) and autocorrelation function (below) of a single soliton from OIM port. The zoom-in image in the inset indicates that the laser operates in a period-2 state. b The reconstituted spectra of the round trips by the white dashed line in a (RTs ~4900–4903). Compared with single-port observation, multi-port observation can reflect more details of soliton evolution from period-1 to period-2. c The real-time evolution process (above) and autocorrelation function (below) of multiple solitons from OIM port. d The reconstituted spectra of the round trips by the white dashed line in (c) (RTs ~901–904). The spectra and evolution processes are similar to those of single solitons, except that the spectra show obvious comb-like modulation. e The complete evolution of the spectra (above) and the time domain (below) in the cavity from simulation. f The 3D diagram shows a more clearly intracavitary evolution dynamics and the multi-port observation captures the important spectral features.
