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 …

We review basic physics and novel types of optical angular momentum. We start with a
theoretical overview of momentum and angular momentum properties of generic optical …

Scientists have known for more than a century that light possesses both linear and angular
momenta along the direction of propagation. However, only recent advances in optics have …

Maxwell's equations, formulated 150 years ago, ultimately describe properties of light, from
classical electromagnetism to quantum and relativistic aspects. The latter ones result in …

We demonstrate experimentally that a photonic crystal made of Al 2 O 3 cylinders exhibits
topological time-reversal symmetric electromagnetic propagation, similar to the quantum …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

The polarization singularity in momentum space has recently been discovered as a new
class of topological signatures of Bloch modes in photonic crystal slabs concerning the far …
