Abstract :
Very high-speed, stable picosecond optical pulses are generated from an active harmonic mode-locked Er3+-doped fibre laser with a 16 m long polarisation maintaining ring cavity. Resultant transform-limited, 3.5-10 ps optical pulses with a time-bandwidth product of 0.31-0.33, are analysed at repetition rates from 2 to 20 GHz. The authors confirm bit-error-free stable operation at up to 8 Gbit/s.
