In order tocope with the ever-growing Internet traffic, high-speed optical interconnects are becoming indispensable. Silicon photonicsis emerging as a key technology for such inter-connects. In this paper, we demonstrate 56 Gb/s nonreturn to zeroon-off keying (NRZ-OOK) direct modulation based on a high bandwidth heterogeneously integrated III-V-on-silicon distributed feedback laser, as well as transmission over 2 km single mode fiber. Using a very similar device, but with electrically isolated and reversely biased tapers, we obtain compact electroabsorption modulation at 56 Gb/s NRZ-OOK as well.
