Abstract :
The fabrication and performance characteristics of a colliding pulse mode locked semiconductor laser which operates near 10 GHz repetition rate is reported. In the laser, a saturable absorber is placed in the middle of the optical cavity. The mode locked pulses from opposite directions arrive at the saturable absorber at the same time, which saturates the absorber faster and hence a shorter pulse could be obtained. The laser performance was examined further by modulating the end amplifiers in addition to the saturable absorber with the same modulation current. In this case, the pulse width as a function of the phase difference between the two currents was measured
