摘要

A 1.56 μm passively mode-locked laser diode with a two-section tensile strained multi-quantum-well structure is fabricated.Without any external pulse compression,a Lorentz pulse train with a pulse width of 1.03 ps and a repetition rate of 35.6 GHz is obtained,which is one of the best results that have been reported on similar devices.The optical pulse has a 300 kHz line width and a 50dB peak over the noise floor in the photodetected radio-frequency electrical spectrum.
