In the last decades, unprecedented progress in the manipulation of the spin angularmomentum (SAM) and orbital angular momentum (OAM) of light has been achieved, enabling anumber of applications, ranging from classical and quantum communication to optical microscopy andsuper-resolution imaging. Metasurfaces are artificially engineered 2D metamaterials with designedsubwavelength-size building blocks, which allow the precise control of optical fields with unparalleledflexibility and performance. The reduced dimensionality of optical metasurfaces enables new physicsand leads to functionalities and applications that are remarkably different from those achievable withbulk materials. In this review, we present an overview of the progress in optical metasurfaces forthe manipultation of SAM and OAM of light, for applications in integrated spin-orbit conversion(SOC) devices.
