Abstract
Structured light beams, such as optical vortices, vector beams, and non-diffracting beams, have been recently studied in a variety of fields, such as optical manipulations, optical telecommunications, nonlinear interactions, quantum physics, and 'super resolution' microscopy.. Their unique physical properties, such as annular intensity profile, helical wavefront and orbital angular momentum, give rise to a plethora of new, fundamental light-matter interactions and device applications. Recent progress in nanostructured materials, including metamaterials and metasurfaces, opened new opportunities for structured light generation on the microscale that exceed the capabilities of bulk-optics approaches such as computer generated holography and diffractive optics. Furthermore, structured optical fields may interact with matters on the subwavelength scale to yield new physical effects, such as spin-orbital momentum coupling. This special issue of Optics Express focuses on the state-of-the-art fundamental research and emerging technologies and applications enabled by the interplay of "structured light" and "structured materials".
Highlights

We provide a short introduction for each paper and classify them into several categories as follows: Orbital angular momentum 25 years on This invited review article of orbital angular momentum is presented by Padgett in [1]
Structured light is expected to propagate though the air turbulence with less degradation than conventional light beams
Summary
Structured light is expected to propagate though the air turbulence with less degradation than conventional light beams. Li et al [2] establish the model to investigate oceanic turbulence effects on the received probability density and crosstalk of OAM modes. The authors show that anisotropic oceanic turbulence effects are smaller than those of isotropic oceanic turbulence under the same condition. They point out the possibility to decrease the effects of turbulence on the received probability of OAM modes by tuning the wavelength and the transverse aperture of the Hermite-Gaussian vortex beam in the source’s plane
