| Abstract: | We present monolithic quantum-dot vertical-cavity surface-emitting lasers (QD VCSELs) operating in the 1.3-/spl mu/m optical communication wavelength. The QD VCSELs have adapted fully doped structure on GaAs substrate. The output power is /spl sim/330 /spl mu/W with slope efficiency of 0.18 W/A at room temperature. Single-mode operation was obtained with a sidemode suppression ratio of >30 dB. The modulation bandwidth and eye diagram in 2.5 Gb/s was also presented. |
