Abstract To exploit the full potential of the transverse spatial structure of light using the Laguerre–Gaussian basis, it is necessary to control the azimuthal and radial components of the photons. Vortex phase elements are commonly used to generate these modes of light, offering precise control over the azimuthal index but neglect the radially dependent amplitude term which defines their associated corresponding transverse profile. Here we experimentally demonstrate the generation of high…

Arbitrary polarization conversion for pure vortex generation with a single metasurface

Abstract The purity of an optical vortex beam depends on the spread of its energy among different azimuthal and radial modes, also known as ℓ $\ell $ - and p-modes. The smaller the spread, the higher

Nanostructured silica spin–orbit optics for modal vortex beam shaping

Abstract Modality is a generic concept of wave-optics at the basis of optical information and communications. One of the challenges of photonics technologies based on optical orbital angular momentum

Entangled ripples and twists of light: radial and azimuthal Laguerre–Gaussian mode entanglement

It is well known that photons can carry a spatial structure akin to a ‘twisted’ or ‘rippled’ wavefront. Such structured light fields have sparked significant interest in both classical and quantum

Dielectric metasurfaces for complete and independent control of the optical amplitude and phase

All-dielectric metasurface holograms with independent and complete control of the amplitude and phase at up to two optical frequencies simultaneously to generate two- and three-dimensional holographic objects are demonstrated.

Laguerre-Gaussian modal q-plates.

Space-variant uniaxial flat optical elements designed to generate pure Laguerre-Gaussian modes with arbitrary azimuthal and radial indices l and p from an incident Gaussian beam are proposed via the combined use of the dynamic and geometric phases.

LaGuerre-Gaussian periodically focusing beams in a quadratic index medium

The Hermite-Gaussian periodically focusing beam solutions of the scalar paraxial wave equation with quadratic index variation are appropriate for rectangular coordinates. One expects the solutions

Laguerre-Gaussian quasi-modal q-plates from nanostructured glasses

A quasi-modal version of the recently introduced Laguerre-Gaussian modal q-plates [Rafayelyan and Brasselet, Opt. Lett. 42, 1966–1969 (2017)] is proposed and implemented using femtosecond direct

Optical vortices 30 years on: OAM manipulation from topological charge to multiple singularities

The authors survey the steady refinement of techniques used to create optical vortices, and explore their applications, which include sophisticated optical computing processes, novel microscopy and imaging techniques, the creation of ‘optical tweezers’ to trap particles of matter, and optical machining using light to pattern structures on the nanoscale.

Arbitrary spin-to–orbital angular momentum conversion of light

A metasurface converter for optical states that transforms polarization states into optical angular momentum states and illustrates a general material-mediated connection between SAM and OAM of light and may find applications in producing complex structured light and in optical communication.

Incorporation of a metasurface that involves spin-orbit interaction phenomenon into a laser cavity provides a route to the generation of spin-controlled intracavity modes with different topologies.
