Beyond the traditional physical dimensions of lightwaves such as complex amplitude, time, frequency and polarization, the spatial structure, the only known physical dimension left, has attracted increasing interest in recent years. Tailoring the spatial structure of lightwaves produces structured light, also known as tailored light, shaped light, sculpted light or custom light. Structured light with spatially variant amplitude, phase and polarization has grown into a significant field, giving rise to many developments in optical manipulation, microscopy, imaging, metrology, sensing, astronomy, nonlinear interactions, quantum science and optical communications. This symposium aims to explore the fundamentals and applications of structured light including but not limited to:
• Basic theories and fundamental properties of structured light
• Spin angular momentum (SAM), orbital angular momentum (OAM), spin-orbital interaction
• Various kinds of structured light (OAM beam, Laguerre-Gaussian beam, Hermite-Gaussian beam, Bessel beam, Airy beam, vector beam, etc.)
• Comparison of different structured light
• Structured light in complex medium (free space, underwater, fiber, etc.)
• Devices and techniques for structured light generation, manipulation and detection
• Metasurfaces, sub-wavelength structures, photonic integrated circuits shaping structured light
• Structured light enabled applications (manipulation, trapping, tweezer, microscopy, imaging, sensing, astronomy, nonlinear interactions, quantum science, optical communications, etc.)

Title: Structured light in turbulence
Abstract: When structured light passes through atmospheric turbulence the amplitude, phase and polarisation structure changes, a severe problem in mode division multiplexing over free space. In this talk I will review our present understanding of classical and quantum light through turbulence, with particular emphasis on whether there exists a resilient set of structured light modes.

Titie: Few mode fibers: modeling and characterization
Abstract: The talk focuses on the analysis of the influence that perturbations like birefringence and ellipticity may have in mode coupling in few mode fibers and on some preliminary characterization based on reflectometric techniques.

Titie: Singular optical beam multiplexing communication towards high performance computing applications.
Abstract: The singular optical beams, referring to the orbital angular momentum and cylindrical vector beam, provide a new degree of freedom for multiplexing optical communication. Here, we review our recent work about the singular optical beams multiplexing for free-space, optical fiber and integrated optical communication towards applications in high performance computing (HPC).
