Abstract :
High-efficiency, high-speed, tapered-oxide-apertured 980 nm vertical-cavity surface-emitting lasers (VCSELs) with 35 Gbit/s error-free operation have been demonstrated. This is the highest data rate reported for directly modulated VCSELs to date. The devices are also highly efficient, showing a record-high data-rate/power-dissipation ratio of 3.5 Gps/mW.
