Résumé

This article reports the improvement of broad area lasers epitaxially grown on InP(311)B substrate. Thanks to optimized growth techniques, a high density of uniformly sized InAs quantum dots (QDs) up to 10¹¹ cm^-2 is obtained. The device, which contains only two stacks of QDs, exhibits a ground state laser emission at 1.54 μm at room temperature associated with a threshold current density as low as 1.70 A/cm². Experimental results also demonstrate a modal gain greater than 8 cm^-1 per QD plane.
