All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

BACKGROUND Optical vortices provide one of the promising solutions for enhancing the
capacity of data multiplexing to meet an unprecedented growth in big data and internet traffic …

Structured light with inhomogeneous phase, amplitude, and polarization spatial distributions
that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can …

Today, it is well known that light possesses a linear momentum that is along the propagation
direction. Besides, scientists also discovered that light can possess an angular momentum …

Structured light recently highlighted the higher-dimensional control with many tailored
degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular …

Spatiotemporal vortices of light, featuring transverse orbital angular momentum (OAM) and
energy circulation in the spatiotemporal domain, have received increasing attention recently …

Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents a
major goal of the everlasting pursue of ultra-fast information transmission and processing as …
