By measuring the complex optical spectrum using a half-rate, sinusoidal modulation method, a mode locked quantum-dash Fabry-Perot laser is characterized for free-running operation and actively mode-locked operation by injection of a 40 Gb/s RZ-OOK signal.
We report on a numerical investigation of the nonlinear dynamics of a passively mode-locked fiber laser containing a long period fiber grating. The model is based on the normalized complex Ginzburg-Landau equation and the nonlinear coupled mode equations of the grating. The numerical results indicate the existence of passive mode-locking and autosoliton generation in the cavity of the laser. Both...
