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 …

Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

Structured light beams have rapidly advanced over the past few years, from specific spatial-
transverse/longitudinal structure to tailored spatiotemporal structure. Such beams with …

Nonlinear holography has been identified as a vital platform for optical multiplexing
holography because of the appearance of new optical frequencies. However, due to …

The discovery of optical transverse orbital angular momentum (OAM) has broadened our
understanding of light and is expected to promote optics and other physics. However, some …

Orbital angular momentum (OAM) carried by helical light beams is an unbounded degree of
freedom that offers a promising platform in modern photonics. So far, integrated sources of …

We report on the thermalization of light carrying orbital angular momentum in multimode
optical fibers, induced by nonlinear intermodal interactions. A generalized Rayleigh-Jeans …
