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…
Quantum-limited optical time transfer for future geosynchronous links
Emily D. Caldwell, Jean-Daniel Deschenes, Jennifer Ellis +5
The combination of optical time transfer and optical clocks opens up the possibility of large-scale free-space networks that connect both ground-based optical clocks and future spa…
The Time Programmable Frequency Comb: Generation and Application to Quantum-Limited Dual-Comb Ranging
Emily D. Caldwell, Laura C. Sinclair, Nathan R. Newbury +1
The classic self-referenced frequency comb acts as an unrivaled ruler for precision optical metrology in both time and frequency. Two decades after its invention, the frequency com…
Optical Atomic Clock Comparison through Turbulent Air
Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32
We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Amplified noise nonstationarity in a mode-locked laser based on nonlinear polarization rotation
Carlos Andres Perilla Rozo, Philippe Guay, Jean-Daniel Deschênes +1
Beat note measurements between a mode-locked and a continuous-wave laser as well as between two mode-locked sources were used to demonstrate that the sub-threshold, cavity filtered…
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…
Femtosecond Optical Two-Way Time-Frequency Transfer in the Presence of Motion
Laura C. Sinclair, Hugo Bergeron, William C. Swann +5
Platform motion poses significant challenges to high-precision optical time and frequency transfer. We give a detailed description of these challenges and their solutions in comb-b…
Time Synchronization over a Free-Space Optical Communication Channel
Isaac Khader, Hugo Bergeron, Laura C. Sinclair +3
Free space optical (FSO) communication channels are typically used to transmit high-speed data between sites over the air. Here we repurpose an FSO digital communication system and…
The evolution of the UV-to-mm extragalactic background light: evidence for a top-heavy initial mass function?
William. I. Cowley, Cedric G. Lacey, Carlton M. Baugh +3
We present predictions for the UV-to-mm extragalactic background light (EBL) from a recent version of the GALFORM semi-analytical model of galaxy formation which invokes a top-heav…
An open and flexible digital phase-locked loop for optical metrology
Alex Tourigny-Plante, Vincent Michaud-Belleau, Nicolas Bourbeau-Hébert +3
This paper presents an open and flexible digital phase lock loop optimized for laser stabilization systems. It is implemented on a cheap and easily accessible FPGA-based digital el…
Comparing optical oscillators across the air to milliradians in phase and in frequency
Laura C. Sinclair, Hugo Bergeron, William C. Swann +3
We demonstrate carrier-phase optical two-way time-frequency transfer (carrier-phase OTWTFT) through the two-way exchange of frequency comb pulses. Carrier-phase OTWTFT achieves fre…
Self-corrected chip-based dual-comb spectrometer
Nicolas Bourbeau Hébert, Jérôme Genest, Jean-Daniel Deschênes +4
We present a dual-comb spectrometer based on two passively mode-locked waveguide lasers integrated in a single Er-doped ZBLAN chip. This original design yields two free-running fre…
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…
