Abstract
The optical gain and the differential gain of a quantum dot gain region in a gain section of a passive or hybrid mode-locked laser is varied by stacking at least two planes of quantum dots. All quantum dot planes are preferably formed by the same fabrication method and under the same fabrication conditions. The number of stacked planes of quantum dots is selected such that the optical gain and the differential gain are both in their optimal range with respect to the optical loss in the laser resonator and to the differential gain in the saturable absorber element. This results in a device with a short pulse width, stable mode-locking, high-power, and temperature-independent operation.
