The concepts of spin and orbital angular momentum of light and the phenomena leading to their interaction are reviewed here, with a focus on those aspects that are most relevant for optical communication.

Next, among the various classes of non-paraxial spin-orbit effects, I focus on those falling under the name of “spin-Hall effect of light”, in particular on the role of these effects for the confined optical modes traveling in optical fibers. A range of potential applications of these spin-orbit optical phenomena for classical and quantum optical communication are finally reviewed.

Abstract

The concepts of spin and orbital angular momentum of light and the phenomena leading to their interaction are reviewed here, with a focus on those aspects that are most relevant for optical communication. I introduce a classification of spin-orbit optical phenomena in two main categories: paraxial and non-paraxial effects. I then describe the theory of spin-orbit effects occurring for paraxial waves traveling through inhomogeneous birefringent media, such as for example q-plates or meta-surfaces. Next, among the various classes of non-paraxial spin-orbit effects, I focus on those falling under the name of “spin-Hall effect of light”, in particular on the role of these effects for the confined optical modes traveling in optical fibers. A range of potential applications of these spin-orbit optical phenomena for classical and quantum optical communication are finally reviewed.
