Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

Efficient nonlinear optical interactions are essential for many applications in modern
photonics. However, they typically require intense laser sources and long interaction …

Metamaterials constructed from deep subwavelength building blocks have been used to
demonstrate phenomena ranging from negative refractive index and ε-near-zero to cloaking …

Twenty-five years ago Allen, Beijersbergen, Spreeuw, and Woerdman published their
seminal paper establishing that light beams with helical phase-fronts carried an orbital …

Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

The orbital angular momentum (OAM) intrinsically carried by vortex light beams holds a
promise for multidimensional high-capacity data multiplexing, meeting the ever-increasing …

An optical vortex having an isolated point singularity is associated with the spatial structure
of light waves. A polarization vortex (vector beam) with a polarization singularity has …

Orbital angular momentum (OAM), which describes the “phase twist”(helical phase pattern)
of light beams, has recently gained interest due to its potential applications in many diverse …

Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

Quantum teleportation provides a 'disembodied'way to transfer quantum states from one
object to another at a distant location, assisted by previously shared entangled states and a …
