CLEO®/Europe-EQEC 2019 Joint Symposia Topics

JSI – Free Electron Lasers and Applications

 Paul Prucnal, Princeton University, USA and Peter Bienstman, University of Ghent, Belgium
Free-electron lasers are rapidly developing novel light sources, pushing the frontiers of time-resolved experiments and non-linear optics into the short-wavelength regime. The intense, femtosecond ultraviolet and x-ray light pulses from free-electron lasers have led to many new discoveries in a wide spectrum of applications, ranging from atomic and condensed matter physics to chemistry, and to materials, biological, and high-energy density sciences. Novel two-color two-pulse modes enable x-ray/x-ray pump/probe experiments with femtosecond resolution. Fully coherent pulses open the door for quantum control approaches involving inner-shell levels. High-repetition rate operations from superconducting accelerators are becoming available allowing to pursue photon-hungry experiments such as ultrafast inelastic scattering. The JS will start with a tutorial on free-electron lasers and bring together scientists from the optical to the ultraviolet and x-ray spectral regime.
JSII – Advanced Microscopy and Nanoscopy
Melike Lakadamyali, ICFO, Castelldefels (Barcelona), Spain
Pietro Ferraro, CNR, Istituto di Fotonica e Nanotecnologie, Trento, Italy
Microscopy, and more generally imaging, is becoming a ubiquitous tool that is useful in any branch of science and technology, spanning from the field of life sciences to materials and nanotechnologies. The recording and processing of optical signals are two main issues to consider for developing and exploiting novel advanced methodologies. Actual sensors and detectors can record a large amount of data, extremely rich in information. This information is convoluted in different ways, depending on the optical configurations adopted. New strategies for extracting useful information are currently under investigation in all labs around the world. Consequently computational aspects are becoming the essence of novel emerging and future advanced microscopy and imaging approaches. Novel computational policies and processing embrace all the most advanced approaches in microscopy for extracting and analysing information from complex optical signals and advanced photonics probes. Hence, new efforts are directed towards modelling and fabricating advanced photonic tools, devices and imaging modalities and by combining nanolenses, scanning probe microscopy with computational aspects for infringing the barriers of resolution of classical microscopy, thus opening the route for a reliable inspection of world at nanoscale.
The topic will be organised in two sessions, named “Tomography and computational imaging” and “Superresolution nanoscopy”, respectively.
The first session will be devoted to cutting-edge strategies for retrieving tomographic data for full-characterization, especially those applied to biological samples. This topic is of great importance for real-world needs in future biomedical applications. The presentations will cover 3D full characterization of cells in static conditions, as well as in-flow along microfluidic channels, and this will pave the way for identification of blood disease or the identification and sorting of tumour cells. Accurate analysis of flowing blood will be also reported by accessing to a new modality in 4 dimensions. 
The second session will address the fundamental issues of superresolution and nanoscopy with the aim of debating the most recent advancements and achievements in microscopy and imaging at the nanoscale. In fact, “superresolution” and “nanoscopy” are the two most important pillars of imaging at the nanoscale in the future. Results on imaging whole cells in 3D with sub-20nm resolution in live-modality will be presented. Further contributions will address the imaging of protein structures by advanced fluorescent microscopy and the modelling and application of superlenses inspired by Mother Nature.

JSIII – Photonics in Cancer Detection and Therapy
Katia Parodi, Ludwig-Maximilians-Universität, Munich, Germany
Nick Stone, University of Exeter, United Kingdom
Cancer is a major societal challenge with a steady increase of incidence, threatening to soon become the leading cause of death in developed countries. Hence, improvements in diagnostic and therapeutic approaches can play a fundamental role in the fight against cancer, to increase the probability of a successful cure. In this context, several promising applications of photonics are emerging, which cover the entire spectrum from highly sensitive spectroscopy for early cancer detection and identification of relevant biomarkers, up to efficient generation of different types of radiation for diagnostic imaging and, ultimately, therapy.  
This symposium will provide an overview of the perspectives offered by modern photonics in cancer detection and therapy. These will include novel light based biomedical imaging and spectroscopic approaches; light mediated therapeutics and innovative laser-developments likely to have an impact in this field. Contributions are expected to address the important link between laser-based technologies and their rapidly increasing biomedical applications.
Topics will include, but are not limited to: highly-sensitive detection of biomolecules and molecular fingerprinting; nanophotonics and nanoparticles for detection and treatment of malignancies; generation of compact sources of THz and X-ray radiation for diagnostic imaging; laser-driven acceleration of electrons and protons or ions for targeted therapeutic applications. 

JSIV – Topological Insulators in Optics
Alberto Amo, CNRS – Laboratoire de Photonique et Nanostructure, Marcoussis, France
Alexander Szameit, Institute of Applied Physics, Jena, Germany
The discovery of topological insulators relying on spin-orbit coupling in condensed matter systems has created much interest in various fields, including in photonics. In two-dimensional electronic systems, topological insulators are insulating materials in the bulk, but conduct electric current on their edges such that the current is completely immune to scattering. Demonstrating such effects in optics poses a major challenge because photons are bosons, which fundamentally do not exhibit fermionic spin-orbit interactions (i.e., Kramer’s theorem). The field of topological photonics has emerged calling for original strategies to overcome this problem. Photonic topological insulators would have enormous potentialities in the lossless transport of photons. For example, topological protected devices could act as compact optical isolators and solve insertion loss problems in wave guiding structures, overcome the key limitation from disorder and localization in slow light and coupled resonator waveguides, and could decrease the power requirements of classical signals and improve coherence in quantum links. 
In parallel to these features, the flexibility of photonic platforms provides an excellent playgroung to investigate topological properties from a fundamental point of view. The engineering of parity-time symmetric Hamiltonians, nodal Weyl points, the topological properties of quasi-crystals, the interplay of nonlinearity and topology or fractional quantum Hall physics are among the research lines recently emerging.
Much like the field of topological insulators in electronics, topological photonics promises an enormous variety of breakthroughs in both fundamental physics and technological outcomes.
This symposium will provide an overview of novel achievements in the field of topological photonics. Topics will include, but are not limited to: photonic topological insulation, nonlinear topological effects, non-hermitian topological effects, photonic spin-orbit coupling, non-reciprocity
