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 …

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 …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

The orbital angular momentum is a fundamental degree of freedom of light wavefronts,
currently exploited in applications where information capacity is a key requirement, such as …

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 …

Optical elements that convert the spin angular momentum (SAM) of light into vortex beams
have found applications in classical and quantum optics. These elements—SAM-to–orbital …

Here we present a roadmap on Photonic metasurfaces. This document consists of a number
of perspective articles on different applications, challenge areas or technologies underlying …

The coupling of waves between the piezoelectric generators, detectors, and propagating
media is challenging due to mismatch in the acoustic properties. The mismatch leads to the …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

Polarized Light and Optical Systems presents polarization optics for undergraduate and
graduate students in a way which makes classroom teaching relevant to current issues in …
