Upconversion Dual-comb Passive Spectroscopy of Mid-IR Incoherent Light
Mingchen Liu, Matthew Heyrich, Sichong Ma +1
We introduce cross-comb correlation spectroscopy, which correlates signals from asynchronous sum-frequency sampling of mid-IR incoherent light with two near-IR combs. We experiment…
Integrated ytterbium gain for visible-near-infrared photonics
Tianyi Zeng, Erik W. Masselink, Tsung-Han Wu +9
Rare-earth gain media form the foundation of modern optical communications, emerging quantum hardware, and ultrafast optics. While chip-scale integration can enable fiber-like, and…
Visible dual-comb spectroscopy across more than 100 THz with lithium niobate nanophotonic waveguides
Carter Mashburn, Kristina F. Chang, Michael J. Wahl +11
Broadband and high-resolution spectroscopy in the visible and ultraviolet is central to advances in multiple fields, including fundamental quantum physics, biology, atmospheric sci…
Photonic Generation and Free-Space Distribution of Millimeter Waves for Portable Optical Clocks
Dylan Meyer, Alexander Lind, William Groman +7
Robust and portable optical clocks promise to bring sub-picosecond timing instability to smaller form factors, offering possible performance improvements and new scenarios for posi…
Ultralow noise microwaves with free-running frequency combs and electrical feedforward
Takuma Nakamura, William Groman, Qing-Xin Ji +11
Optically generated microwave signals exhibit some of the lowest phase noise and timing jitter of any microwave-generating technology to date. The success of octave-spanning optica…
Dual-comb correlation spectroscopy of thermal light
Eugene J. Tsao, Alexander J. Lind, Connor Fredrick +8
The detection of light of thermal origin is the principal means by which humanity has learned about our world and the cosmos. In optical astronomy, in particular, direct detection…
