简介
Traditionally, the high-performance optical coherent communication TX has been a discrete assembly based on LiNbO 3 modulators and III-V drivers. While delivering high bandwidth (BW) and linearity, such a platform is bulky and does not work for high-volume or intra-datacenter applications. Silicon photonics (SiPh) offers a Si-based platform for next-generation transceivers by integrating all required optical functions. But even in existing SiPH-based commercial modules, the driver generally remains a III-V-based chipset, impeding the path to an all-silicon solution. The challenge for an all-silicon-based coherent optical TX is in the simultaneous requirement of high differential voltage swing (V ppd ), linearity and BW. In this work, we present a 130nmSiGe driver achieving a 6V ppd swing, 3.6% THD and small-signal BW over 40GHz. Co-packaged with a SiPh transceiver, the driver enables the same level of performance as …
