Paper Abstract

Effect of the initial chirp on picosecond pulse breakup in the presence of noise is analyzed through numerically solving the modified nonlinear Schrödinger equation, using the standard split-step Fourier method. It is found that, for shorter pulses, the pulse breakup is caused by pulse collapse resulted from high-order soliton compression, even in the presence of noise. For longer pulse, pulse breakup is triggered by nonlinear amplification of noise caused by modulation instability. The effect of initial chirp on pulse breakup is closely related to the mechanism of pulse breakup, and the process of short pulse breakup depends strongly on the strength of negative initial chirp.
