Description du projet
Nouvelles techniques de traitement optique pour l’imagerie et la métrologie disruptives
Un nouveau domaine de recherche prometteur, qui fusionne l’optique non linéaire ultrarapide et l’imagerie informatique, se profile à l’horizon. En combinant des composants optiques intégrés et à fibres, il sera possible d’explorer de nouvelles dynamiques non linéaires multimodes et dépendantes de l’entrée via des schémas d’apprentissage automatique dédiés. Tel est l’objectif du projet STREAMLINE, financé par l’UE, qui constitue un ambitieux programme pluridisciplinaire visant à faire avancer le développement de sources photoniques intelligentes. Les systèmes photoniques actuels reposent principalement sur des processus optiques non linéaires complexes à la base d’applications exigeantes couvrant le développement de sources lumineuses avancées, la métrologie et l’imagerie. Cependant, les moyens de contrôler les phénomènes et les interactions non linéaires sont plutôt limités, tandis qu’il peut être difficile d’atteindre les paramètres idéaux pour une application spécifique. STREAMLINE va changer cette situation en proposant des techniques de traitement optique disruptives susceptibles de permettre des approches innovantes en matière d’imagerie et de métrologie.
Objectif
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 tunability: 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 will unlock access to novel deep-learning strategies towards biological sample histology.
