Abstract :
In this paper, noise effects related to pulsed injection locking of a passively modelocked laser (PML) are analyzed. A set of nonlinear equations, derived from a soliton perturbation method, is used to describe the modelocked laser pulse evolution, under injection locking. The equations are linearized, and the stability of the injection locked solution is studied. Subsequently, the linear equations are employed to describe the coupling of both the injected signal noise and the internal noise, to the locked pulses. Noise reduction due to the injection process is demonstrated, with important implications for all optical signal regeneration and synchronization
