Rapid progress in the research and development of optical frequency comb sources has opened new possibilities in communications, ranging from replacing a multitude of parallel lasers by a single multi-line source to employing wideband coherence to enhance nonlinearity mitigation. The workshop will discuss whether these advances can translate into practical systems by addressing key questions including:

• What are the benefits, drawbacks, and challenges of single-source communications?

• Do expected power/complexity reductions justify possible reliability issues (single source failure)? How to increase reliability? What are the options for ultra-narrow linewidth seed laser?

• What power or OSNR per comb line is acceptable? What linewidths are required?

• What are the tradeoffs in comb source choices: fiber versus integrated, mode-locked versus parametric, travelling-wave versus oscillator?

• What are the options for monolithic or hybrid integration with other components, e.g., (de)multiplexers and modulators?

• What are the prospects of using optical frequency combs in data center networks?
