Abstract :
Small-dimension power-efficient high-speed oxide-confined 980 nm vertical-cavity surface-emitting lasers (VCSELs) with record-high bandwidth/power-dissipation ratio of 12.5 GHz/mW have been demonstrated. The devices show a modulation bandwidth of 15 GHz at a bias current 0.9 mA, corresponding to only 1.2 mW power dissipation
