Broadband dual-comb hyperspectral imaging and adaptable spectroscopy with programmable frequency combs
Fabrizio R. Giorgetta, Jean-Daniel Deschênes, Richard L. Lieber +3
We explore the advantages of a free-form dual-comb spectroscopy (DCS) platform based on time-programmable frequency combs for real-time, penalty-free apodized scanning. In traditio…
10 GHz Generation with Ultra-Low Phase Noise via the Transfer Oscillator Technique
Nicholas V. Nardelli, Tara M. Fortier, Marco Pomponio +4
Coherent frequency division of high-stability optical sources permits the extraction of microwave signals with ultra-low phase noise, enabling their application to systems with str…
20 years of developments in optical frequency comb technology and applications
Tara Fortier, Esther Baumann
Optical frequency combs were developed nearly two decades ago to support the world's most precise atomic clocks. Acting as precision optical synthesizers, frequency combs enable th…
Dual-comb spectroscopy with tailored spectral broadening in SiN nanophotonics
Esther Baumann, Eli V. Hoenig, Edgar F. Perez +10
SiN waveguides, pumped at 1550 nm, can provide spectrally smooth, broadband light for gas spectroscopy in the important 2 m to 2.5 m atmospheric wat…
Measurement of the impact of turbulence anisoplanatism on precision free-space optical time transfer
W. C. Swann, M. I. Bodine, I. Khader +4
Future free-space optical clock networks will require optical links for time and frequency transfer. In many potential realizations of these networks, these links will extend over…
High Coherence Mid-Infrared Dual Comb Spectroscopy Spanning 2.6 to 5.2 microns
Gabriel Ycas, Fabrizio R. Giorgetta, Esther Baumann +4
Mid-infrared dual-comb spectroscopy has the potential to supplant conventional high-resolution Fourier transform spectroscopy in applications that require high resolution, accuracy…
Synchronization of Distant Optical Clocks at the Femtosecond Level
Jean-Daniel Deschenes, Laura C. Sinclair, Fabrizio R. Giorgetta +6
The use of optical clocks/oscillators in future ultra-precise navigation, gravitational sensing, coherent arrays, and relativity experiments will require time comparison and synchr…
Frequency Comb-Based Remote Sensing of Greenhouse Gases over Kilometer Air Paths
Gregory B. Rieker, Fabrizio R. Giorgetta, William C. Swann +10
We demonstrate coherent dual frequency-comb spectroscopy for detecting variations in greenhouse gases. High signal-to-noise spectra are acquired spanning 5990 to 6260 cm^-1 (1600 t…
Optical two-way time and frequency transfer over free space
Fabrizio R. Giorgetta, William C. Swann, Laura C. Sinclair +3
The transfer of high-quality time-frequency signals between remote locations underpins a broad range of applications including precision navigation and timing, the new field of clo…
