Monolithic strained‐InGaAsP multiple‐quantum‐well lasers with integrated electroabsorption modulators for active mode locking

Active mode locking by monolithic lasers with integrated electroabsorption modulators using strained‐InGaAsP multiple quantum wells is described. The electroabsorption modulator acts as a short optical gate when a sinusoidal voltage is driven at a deep bias point. Pulse widths as short as 2 ps have been obtained at a repetition rate of 16.3 GHz for a 2.5‐mm‐long monolithic laser.
