Squeezed dual-comb spectroscopy Open
Laser spectroscopy and interferometry have provided an unparalleled view into the fundamental nature of matter and the universe through ultra-precise measurements of atomic transition frequencies and gravitational waves. Optical frequency …

Dual-comb correlation spectroscopy of thermal light Open
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 of thermal photons and the resolution of their spectra have…

Quantum theory of temporally mismatched homodyne measurements with applications to optical-frequency-comb metrology Open
The fields of precision timekeeping and spectroscopy increasingly rely on\noptical frequency comb interferometry. However, comb-based measurements are not\ndescribed by existing quantum theory because they exhibit both large mode\nmismatch…

A Multi-Harmonic NIR-UV Dual-Comb Spectrometer Open
Dual-comb spectroscopy in the ultraviolet (UV) and visible would enable broad bandwidth electronic spectroscopy with unprecedented frequency resolution. However, there are significant challenges in generation, detection and processing of d…

Photonic Flywheel in a Monolithic Fiber Resonator Open
We demonstrate the first compact photonic flywheel with sub-fs time jitter (averaging times up to 10 μs) at the quantum-noise limit of a monolithic fiber resonator. Such quantum-limited performance is accessed through novel two-step pumpin…
