Monolithic multiple colliding pulse mode-locked quantum-well lasers, experiment and theory

Abstract

We report here on a monolithic multisectioned quantum-well laser that operates as multiple colliding pulse mode-locking source. With this type of operation several pulses are present within a laser simultaneously and it produces high-repetition rate pulse trains (up to 375 GHz) and pulse techniques of around 1-3 ps, as deduced from linear correlation technique measurements. By changing the configuration of the sections 1, 2, 3, or 4 pulse operation can be selected; frequency- and time-domain theories have been developed to explain this type of behavior.< >
