Modulator Technologies for Intra-Datacenter Optical Interconnects Beyond 1Tbps
We review the technology options and challenges of scaling intra-datacenter optical interconnects beyond 1Tb/s. We examine if coherent technology has an immediate future in short reach applications. We provide an overview of the modulator technologies that help us realize this scaling task, with an emphasis on Silicon photonics. Finally, we highlight the importance of tighter electro-optical integration at high baud rates.
