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.

Title: Polarization manipulation of spatially structured light fields in longitudinal direction

Abstract: Polarization singularities, an important branch of singular optics, has attracted considerable amount of research interesting. Here, we discuss the transformation of polarization singularities in the longitudinal direction, and propose several methods to achieve longitudinal manipulation of polarization.
Filippo Capolino, University of California, USA

Title: Structured light for optical magnetic and chiral microscopy

Abstract: Magnetic nanoprobes use structure light and magnetic nanoantennas to enhance magnetic nearfield. They can be used also to enhance chirality detection in conjunction to the new concept of maximum helicity bound applied to structured light. Detection mechanisms based on scattering and photoinduced force will be discussed.

Title: Manipulating the coherence structure of light beam and its applications

Abstract: Manipulating the coherence structure of light beam will induce many extraordinary phenomena, such as self-focusing, self-shaping, self-splitting and super-strong self-reconstruction. In this talk, I will introduce recent progress on light beams with prescribed coherence structure and their applications.

Title: Longitudinally structured light: how to engineer the light along its axis of propagation

Abstract: In this talk I will show that it is possible to engineer “at will” the intensity value, intensity pattern, polarization, wavelength, and local orbital angular momentum of a light beam along its axis of propagation.

Title: Manipulation of light field on plasmonic nanotips and its applications

Abstract: We present a new scheme for background-free intense nanofocusing light source, which is highly demanded for spectroscopy with spatial super-resolution. In this scheme, the light field mode is reconfigured in optical fiber to enable plasmonic nanofocusing at the apex of a metal-coated fiber tip.

Title: Laser remote sensing with complex light fields

Finally, I will present a novel technique to measure simultaneously the transverse and longitudinal velocity components.

Title: Deep-Learning optimised single pixel LiDAR

Abstract: Using deep-learning we design optimum patterns for projecting to a scene and use single-pixel, time-of-flight, detection of backscattered light to obtain 3D images.   This approach makes optimum use of the photons available and gives LiDAR images without need for optical scanning.

Additionally, I will show how machine learning and a conventional camera can be used to analyze spatial modes, precluding the need for more complex optical elements, such as, spatial light modulators.
