Focused Sessions

For the first time, EOSAM includes Focused Sessions, on selected hot topics deemed to be of special interest to conference attendees. Every year, the conference will provide the timely platform to highlight several specific areas that reflect the emerging trends in optics and photonics.

 

Session 1: Specialty optical fibers

Co-chairs

Smektala sq Frédéric Smektala (Univ. Burgundy - Lab. ICB, France)

Synopsis

The well-established field of optical fibers is continuously proving to play a central role in a growing number of modern technologies including applications in defense and security, sensing, automotive, and biomedicine. This special session aims to follow up on advances and innovations in the field of specialty optical fibers and their potential applications, including novel designs, fabrication approaches and characterisation, as well as unconventional materials enabling new functionalities.

 

Topics

  • Infrared fibers
  • microstructured fibers
  • hollow core fibers; soft-glass fibers
  • multi-material fibers
  • functionalized fibers
  • 3D printing and novel technologies for fiber manufacturing and post-processing
  • soft optical fibers
  • semiconductor optical fibers

Session 2: Structured light

Co-chairs

Pierre bejot Pierre Béjot (CNRS - Lab. ICB, France)
Ignacio moreno Ignacio Moreno Soriano (Universidad Miguel Hernández, Spain)
   

 

 

Synopsis

Structured light refers to the generation and application of custom light fields. Initially referring to the traditional manipulation of two-dimensional transverse fields, including optical vortices or vector beams, light structuring has evolved towards the concept of four-dimensional space-time wavepackets. The goal of this session is to review the recent advances made in the field from generation, control and detection of such complex fields to their interactions with matter, providing insights into the current state.

 

Topics

  • Creation, control and detection of structured light
  • optical vortices and singularities
  • orbital angular momentum; space-time wave packets
  • vector beams
  • light coherence
  • time-polarization correlated optical fields
  • interactions of structured light with matter

Session 3: Chiroptical phenomena

Chair

Alessandro belardini sq Alessandro Belardini (Sapienza Univ. di Roma, IT) 
Cyriaque genet Cyriaque Genet (CNRS, FR)
   

 

Synopsis 

Chiroptical phenomena represent a very broad-spectrum research field involving a large number of disciplines, such as physics, chemistry, biochemistry, and life sciences. The applications range from chiroptical sensing of chiral molecules to optical manipulation of proteins with circular polarized light to chiral light generation in compact LEDs and lasers for optical information applications, to name just a few. Enlarged optical chirality within electromagnetic hotspots can lead to enhanced chiroptical phenomena within confined nanoscale volumes, potentially increasing the sensing efficiency by orders of magnitude. This session is open to both fundamental and applied aspects of chiroptical phenomena at all length scales.

 

Topics

  • Chiral metamaterials
  • materials for chiroptical sensing
  • novel theoretical concepts in chiroptical phenomena
  • chiral light states
  • chiral optical forces

Session 4: Machine-​​​​​​​Learning for Optics and Photonic Computing for AI

Co-chairs

Daniel brunner Daniel Brunner (CNRS – FEMTO-ST Inst., France)
Goery genty Goery Genty (Tampere University, Finland)
   

 

Synopsis

In the past few years, artificial intelligence (AI) techniques have opened up new horizons for research into photonics. AI techniques are particularly powerful to design photonics structures and devices for specific tasks, often resulting in higher efficiency and generally improved performance. Photonics components and systems are also exceedingly considered to replace conventional electronic implementations of AI computation. This special session aims cover the most recent findings and scientific insight in advanced techniques and applications of this merger between Photonics and AI.

 

Topics

  • Machine-learning techniques
  • all-optical neural networks
  • AI-related techniques for optical computing. imaging, sensing, and nonlinear optics
  • Photonic AI systems and chips
  • Inverse design of photonics structures and components
