Abstract
In order to cope with the ever-growing internet traffic, high-speed optical interconnects are becoming indispensable. Silicon photonics is emerging as a key technology for such interconnects. In this paper, we demonstrate 56 Gbps Non-Return to Zero On-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 electro-absorption modulation at 56 Gbps NRZ-OOK as well. Related Research Topics
