Non-Newtonian binary pulse interaction in a Mamyshev oscillator

We consider the propagation and binary interactions of optical pulses in an anomalous dispersion Mamyshev oscillator modeled by means of nonlinear Schrödinger equations. Two eigenpulses with different profile and energy can propagate in the cavity. It is found that pulse interaction in the Mamyshev oscillator strongly differs from particle interaction through a potential: the interaction determines the relative pulse velocity, which remains unchanged when pulse separation varies. •Nonlinear Schrödinger equations model an anomalous dispersion Mamyshev oscillator.•Two eigenpulses with different profile and energy can propagate in the cavity.•pulse interaction strongly differs from particle interaction through a potential.
