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…
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…
