Summary

• What is new: Introduction of a fully integrated superconducting microcomb which is easy to manufacture and operates with ultra-low power.
• Why this is important: The need for scalable, energy-efficient, and easily-manufactured integrated frequency combs for on-chip applications.
• What the research proposes: A superconducting microcomb comprising a nonlinear superconducting device, a Josephson junction, coupled to a superconducting microstrip resonator, facilitating coherent comb generation through self-started mode-locking.
• Results: The microcomb operates with low power consumption (tens of picowatts), spans multiple octaves in the microwave domain, and the linewidths of all comb lines can be narrowed to 1 Hz using coherent injection-locking.
