In this paper, we characterize the modulation characteristics of oxide-apertured vertical-cavity InGaAs-GaAs DBR QW lasers. A bandwidth of 15.3 GHz at only 2.1 mA of current with a state-of-the-art modulation current efficiency of 14 GHz/mA/sup 1/2 / is demonstrated for a 3.1 μm diameter device. We show that the intrinsic speed is limited to ∼46 GHz by gain compression and that a 10 GHz parasitic limits current device performance.
