Ingår i: 2023 Conference on Lasers and Electro-Optics, CLEO 2023.
-
Konferensbidrag (refereegranskat)abstract
- Leveraging the Vernier dual-comb method, we self-reference a THz octave-spanning microcomb with fCEO ~100 GHz - normally too high for typical detection equipment - and translate the stability of an RF reference to optical frequencies.

Vernier Microcombs for Future Miniature Yb + Clocks
- 2023
-
Ingår i: 2023 IEEE Photonics Conference, IPC 2023 - Proceedings.
-
Konferensbidrag (refereegranskat)abstract
- We demonstrate an architecture for dualmicrocomb-based readout of an optical clock. Microcombs frequency-divide a compact narrow-linewidth laser, capable of being frequency-doubled to within a few GHz of a 171Yb+ clock transition, to an RF output.

Tidskriftsartikel (refereegranskat)abstract
- Recent developments in Kerr microcombs may pave the way to a future with fully stabilized ultralow size, weight, and power consumption (SWaP) frequency combs. Nevertheless, Kerr microcombs are still hindered by a band-width/repetition rate trade-off. That is, the octave bandwidth needed for self-referencing is typically realized only with similar to THz repetition rates beyond the range of standard commercial photodetectors. The carrier envelope offset fre-quency fCEO is often likewise too high for detection. Dual-comb techniques for the measurement of THz repetition rates have made exciting progress, but the fCEO detection problem remains largely unaddressed. In this work, utilizing a Vernier dual-comb configuration, we demonstrate simultaneous detection of the electronically divided similar to 900 GHz rep-etition rate and similar to 97 GHz carrier envelope offset frequency of an octave-spanning microcomb. This, in turn, could help usher optical atomic clocks, low-noise microwave generators, and optical frequency synthesizers into various real-world applications.Published by Optica Publishing Group under the terms of the Creative Commons Attribution 4.0 License.
