Self-referenced nonlinear interferometry for chromatic dispersion sensing across multiple length scales
Romain Dalidet, Sébastien Tanzilli, Gregory Sauder +2
Chromatic dispersion critically impacts the performance of numerous applications ranging from telecommunication links to ultrafast optics and nonlinear devices, yet fast and precis…
High-resolution broadband characterization of resonance dispersion in an optical microresonator
Romain Dalidet, Adrien Bensemhoun, Gregory Sauder +12
Accurate knowledge of the uneven free spectral range of an optical microresonator, which provides direct insight into group velocity dispersion, is essential for understanding and…
Compact and efficient quantum frequency conversion of a fiber-pigtailed single-photon source
Mathis Cohen, Anthony Martin, Romain Dalidet +9
Quantum frequency converters are key enabling technologies in photonic quantum information science to bridge the gap between quantum emitters and telecom photons. Here, we report a…
Entanglement-based clock syntonization for quantum key distribution networks. Demonstration over a 50 km-long link
Yoann Pelet, Grégory Sauder, Sébastien Tanzilli +2
We present the implementation of a time synchronization protocol as part of an experimentally deployed entanglement-based quantum key distribution (QKD) link. The system is deploye…
Two-photon interference at a telecom wavelength for quantum networking
Mathis Cohen, Laurent Labonté, Romain Dalidet +2
The interference between two independent photons stands as a crucial aspect of numerous quantum information protocols and technologies. In this work, we leverage fiber-coupled devi…
Accurate and precise optical phase sensor based on a non-linear quantum Sagnac interferometer
Romain Dalidet, Laurent Labonté, Gregory Sauder +2
Optical phase measurements play a key role in the detection of macroscopic parameters such as position, velocity, and displacement. They also permit to qualify the microscopic prop…
