The elec. control of the lasing wavelength in two-section quantum dot lasers was studied. By changing the optical loss in the absorber section, the control of the ground-state (GS) and excited-state (ES) lasing thresholds and output powers is achieved. Addnl., a complex self-pulsation dynamics with simultaneous oscillations of the GS and ES intensities is obsd. The exptl. results are well explained in the framework of a rate equation model.
