Abstract
In this work, we numerically investigate the collisions of two counter-propagation creeping dissipative solitons with a single period. We found five different classes of outcomes as a result of such collisions: periodic, fixed shape or quasi-fixed shape, interpenetration, plain pulses bound states with two frequencies, and complex behavior. Recently, the temporal and spectral evolution dynamics of creeping solitons have been experimentally observed in a passively mode-locked fiber laser. In this framework, we assume that our predictions eventually can be useful and verified in laser systems.
