下一代相干数据中心内/间互连目前缺乏降低成本和功耗的明确途径，而成本和功耗是这些数据链路的驱动因素。在这项工作中，解决并评估了与从相干 C 波段到 O 波段硅光子学过渡相关的权衡。讨论包括相干数据链路的基本组件，即光学组件、光纤链路和收发器。作为这些链路的主要组件，我们评估了单片硅光子 BiCMOS O 波段相干接收器的潜在性能，并与类似的 C 波段设备进行了比较。
Upcoming generations of coherent intra/inter data center interconnects currently lack a clear path toward a reduction of cost and power consumption, which are the driving factors for these data links. In this work, the tradeoffs associated with a transition from coherent C-band to O-band silicon photonics are addressed and evaluated. The discussion includes the fundamental components of coherent data links, namely the optical components, fiber link and transceivers. As a major component of these links, a monolithic silicon photonic BiCMOS O-band coherent receiver is evaluated for its potential performance and compared to an analogous C-band device.
