Here, shallow mesa stripe lasers with 265 /spl mu/m cavity length and 6 /spl mu/m mesa width (MOCVD sample) or 550 /spl mu/m cavity length and 8 /spl mu/m mesa width (MBE sample) are used for the resonance frequency measurement. With such a short cavity for a MOCVD sample, the emission stems from the excited states. The threshold current is 21.8 mA and the external quantum efficiency is 55.6 percent. We give the photoluminescent spectrum of our quantum dot laser.
