Free-electron lasers (FEL) offer unique opportunity for the investigation of light-matter interaction in the extreme ultraviolet and X-ray spectral ranges. The symposium aims at bringing together the expertise of FEL developers and the community of users and potential users interested in taking advantage for their research of the unprecedented combination of extreme time resolution (down to the attosecond domain), photon flux and high peak intensities available at FELs. The presentations will focus on the latest developments achieved in the operation of FELs and in selected highlights of user experiments.

Novel seeding concepts; Polarization control of XUV and X-ray pulses; Multi-color and multi-harmonic operation; Light-matter interaction under extreme conditions; Pulse characterization; Time-resolved coherent diffractive imaging; Target development for coherent imaging; High-repetition rate  XUV and X-ray sources; Novel schemes for attosecond pulse generation; Crystallography; Biological imaging; FEL optimization based on machine learning approaches; Theoretical modelling of laser-matter interaction; Multiphoton processes in the XUV and X-ray range; Imaging of ultrafast electronic and nuclear dynamics

Major discoveries in astrophysics are enabled by new technologies that respond to the increasing demand for higher spectral, angular and temporal resolution across a broad wavelength range, pushing the limits of the existing infrastructures. In this regard photonics is playing a growing role.Over the last decades strong ties have been built up between the astronomical instrumentation and photonics communities, which has resulted in unique synergies for astrophysics in the 1-10μm infrared wavelength range. The strength of photonics is in the small-size integration of sophisticated optical functions, which once applied to the field of astronomy contributes to reduce the size and complexity of deployable instruments, as well as to increase their functional stability. Furthermore, while ground-based instruments have already directly benefitted from the power of astrophotonics, space applications might be the next frontier.
The proposed symposium aims at inspiring additional technology exchanges between the fields of astronomy and photonics by sharing new innovative results and ideas that will raise the state of the art of astrophotonics. The following areas will be broadly covered, with a focus on design, manufacturing and performance, as well as on the benefit of miniaturization in view of future integration in a ground- or space-based scientific instrument.

Topics :
Active/Passive Integrated Optics for beam combination and phase control; Integrated photonic spectrographs: FTS and direct detection units; New photonic functionalities for high-contrast science in astronomy; Frequency conversion of photonic correlation of signals; New micro-structured optical fibers for astronomy; Bridging the gap between THz and mid-IR technologies; Advances in ultrafast laser writing for astronomy; Space qualification of photonic devices; Advances in the lithographic platforms; Photonic calibration sources (e.g., frequency combs, fiber etalons…); Platforms and technologies for spectral coverage extended in the UV/VIS/MIR; Wavefront control and photonics – Integrating the detection stage

“Nowadays, there are clear global challenges associated to the vast amounts of energy we consume in processing Big Data using Artificial Intelligence (AI) that are putting our industries and societies at risk. AI operate at high-power penalty since they rely on intensive data-driven deep learning neural networks running in conventional computers. There is a demand for new computing paradigms able to run AIs at extremely low energy per bit budgets. Neuromorphic systems, that can mimic the way the brain process information, are among the most promising technologies. Photonics enables the design of energy-efficient computing approaches such as neuromorphic photonic computing, allowing massively distributed power-efficient architectures for parallel processing and enabling new AI applications as required for the Industrial 5.0 Intelligent era revolution. This symposium covers the status, prospects, and challenges of light-based computing for AI taking advantage of new materials, devices, architectures, software, algorithms and simulation tools.

Topics :
Device, circuit; architecture design; analysis and optimization for neuromorphic photonic computing systems; Emerging materials for devices of neuromorphic photonic computing importance; Hardware photonic accelerators for machine/deep learning; Photonic reservoir computing; Novel neuromorphic photonic computing systems; On-chip learning and inference, learning algorithms and optimizations; Complexity and scalability of neuromorphic photonic computing; Emerging technologies for brain-inspired nanophotonic computing and communication.
