Abstract :
We present monolithically quantum-dot vertical-cavity surface-emitting laser (QD VCSELs) operating in the 1.3 mum optical communication wavelength. The QD VCSELs have adapted fully doped structure on GaAs substrate. The output power is ~ 330 muW with slope efficiency of 0.18 W/A at room temperature. Single mode operation was obtained with side-mode suppression ratio of > 30 dB
