With hyperscaler bandwidth requirements expected to reach into the terabits in the not-too-distant future, a variety of innovations will be necessary in data center optics. These will include optical transceivers at 400G and above as well as optical chip-to-chip interconnect and related co-packaged optics advances. Technologies such as photonic integrated circuits enabled via silicon photonics and other photonic integration strategies will play important roles, as will innovation in lasers. This session will focus on high-speed transmission requirements in the data center and the technologies that will help meet them.
