Single-Photon Level Dispersive Fourier Transform: 

Ultrasensitive Characterization of Noise-Driven Nonlinear Dynamics

Our latest work with the team of Michael Kues (Leibniz University Hannover) is online, and featured in Cover of the ACS Photonics Issue of November 2023.

In this paper, we leverage quantum-inspired dispersive Fourier transform to characterize ultrafast spectral fluctuations with great sensitivity (< fW), high spectral resolution (~50 pm), and excellent dynamic range (up to ~80dB).

A great way to analyze and push forward the study of nonlinear instabilities and incoherent processes in photonics with improved performances.

ERC Starting Grant 2020 awarded

The project STREAMLINE was selected for funding by the ERC

Founded in 2007, the European Research Council (ERC) funds innovative exploratory projects that are likely to generate scientific, technological or societal progress. Evaluated by international experts, the ERC awards individual research grants to scientists based on scientific excellence as sole selection criterion. 

The ERC Starting Grant applies to young researchers (2 to 7 years following completion of a Ph.D) for projects allocated for up to 5 years and with a budget up to 1.5 million euros. In 2020, the success rate of ERC Starting Grant was 13.3%, with recipients spanning 40 nationalities and 25 countries across Europe. In France, 38 projects were selected this year within the total of 3272 proposals received for all disciplines.

Smart phoTonic souRces harnEssing Advanced Multidimensional Light optimization towards machIne-learNing-Enhanced imaging  (STREAMLINE)

Modern photonic systems increasingly rely on complex nonlinear optical processes at the foundation of demanding applications spanning advanced light source development, metrology and imaging. Importantly, current flagship imaging systems are based on nonlinear light-matter interactions provided by specialized lasers requiring complex operation and lacking flexibility: means of controlling nonlinear phenomena and interactions are restricted, and reaching the ideal settings for a specific application can prove extremely challenging.

In this context, optical excitations can be inefficient (with e.g. excessive power or spectral coverage) and versatile means to drive coherent control of light properties are highly sought-after, for they provide the main building blocks for advanced imaging techniques. However, such control is currently constrained to few degrees of freedom provided by complex components ultimately hindering the accessible optical parameter space. The realization of versatile, efficient and practical optical sources in compact forms would thus represent a fundamental revolution.

STREAMLINE constitutes an ambitious multidisciplinary program aiming to push forwards the development of 'smart photonic sources' for the creation of a promising new research field merging ultrafast nonlinear optics and computational imaging.

The envisioned architecture, combining integrated and fibered components, will explore new multimode and input-dependent nonlinear dynamics via dedicated machine-learning schemes

Together with suitable monitoring techniques, fully reconfigurable and tailored optical wavepackets (with ‘on-demand’ spectral, temporal and spatial properties), will be exploited towards disruptive nonlinear imaging and metrology techniques. Besides providing user-friendly operation with improved performances, blueprint dynamical imaging with custom light-matter interactions is expected to unlock access to novel deep-learning strategies towards biological sample histology.
