Energy-selective control of noise-assisted multipulsing by weak optical seeding in the dissipative-soliton-resonance regime
Abstract
We investigate how weak optical injection changes single-pulse operation in a laser in the dissipative-soliton-resonance regime. The energy scans show that a small injected field suppresses multipulsing and extends predominantly single-pulse operation to higher energies. Further increasing the seed power makes this extended range nonuniform: regions of enhanced multipulse formation alternate with regions of suppression. We analyze timing and optical-phase fluctuations of the injection field. At the lowest energies, these fluctuations cause continuous-wave and multipulse generation to dominate the laser output. At the highest energies, injection-field phase fluctuations promote multiple pulses, whereas time fluctuations suppress them. Deterministic calculations without noise or injection show that both single pulses and prepared pulse pairs can persist under the same settings. We show that the spectral entropy of a dissipative soliton reflects changes in individual pulse spectra and pulse interference. It characterizes the probabilistic transition between single- and multipulse regimes, but it does not, by itself, predict in detail which regime the laser will form. Together, the results connect the energy-selective action of optical injection to pulse formation and structure, while distinguishing persistence of a prepared pulse from its formation out of a background.
