5 January 1994 Passive mode locking of solitons using a nonlinear twin-core fiber

We show that mode-locking based on the formation of a fundamental soliton can be accomplished with a nonlinear twin-core fiber added to a homogeneously broadened gain medium within a laser cavity. The transient state towards equilibrium in such a device is characterized by an increase in the spectrum width of the pulse until a steady-state value is reached which is exceeding the gain bandwidth. At steady-state, the linear coupling properties of the twin-core fiber is continuously allowing for the radiated power from the perturbed soliton to exit the laser cavity. The corresponding energy gain per round trip eventually becomes a small perturbation to the soliton which recovers its shape and phase profile within each round trip.
