The operation of a monolithic 5-quantum well, 4-section mode locked semiconductor laser with an integrated distributed Bragg reflector (DBR), which generates 10 ps optical pulses at repetition rate of 10 GHz at a wavelength of 1.55 μm, is investigated. The device is simulated using complete travelling wave model which includes spontaneous and shot noise sources and uses gain parameters independently verified form band calculation models. The jitter is calculated at different delay values. The different contributions to jitter in the laser within the model indicates that spontaneous emission is the dominant cause. The final jitter value and the time constant are investigated.
