The importance of spontaneous emission noise in dynamic jitter in monolithic mode-locked diode lasers

This study has concentrated on 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 /spl mu/m. An account of the observations and to indications as to how components can be optimised for low dynamic jitter operation is given.
