We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in
focusing, scattering, and imaging optical systems. Our theory employs universal geometric …

As a fundamental property of light, the angular momentum of photons has been of great
interest. Here, we demonstrate that optical spin-to-orbital angular momentum conversion …

This book deals with applications in several areas of science and technology that make use
of light which carries orbital angular momentum. In most practical scenarios, the angular …

We demonstrate experimentally an optical process in which the spin angular momentum
carried by a circularly polarized light beam is converted into orbital angular momentum …

We study theoretically and verify experimentally the detailed dynamics of spin-to-orbital
angular momentum conversion for a circularly polarized Gaussian beam propagating along …

It has long been recognized that photons carry spin angular momentum that corresponds to
polarization. During the last two decades, research has revealed that lightwaves can carry …

Spin angular momentum of photons and the associated polarization of light has been known
for many years. However, it is only over the last decade or so that physically realizable …

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 …

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 …

It is well known that the spin angular momentum of light, and therefore that of photons, is
directly related to their circular polarization. Naturally, for totally unpolarized light …
