In this work we report devices that generate a single pure oam state in a single circular polarization channel by waveguide excitation of a microdiskmicroring cavity coupled to a chain of plasmonic antennas figure 1. The existing techniques for measuring highdimensional pure states of light in the orbital angular momentum oam basis either involve a large number of singlepixel data acquisitions and substantial postselection errors that increase with dimensionality, involve substantial loss, or require interference with a reference beam of known phase. This proposed design can therefore scatter a polarizationpure oam state and, by reciprocity, could also be used for oamselective detection and demultiplexing. Three major methods which have been generally employed for the generation of optical beams with orbital angular momentum are discussed, which include the practice of diffractive optics elements, metasurfaces, and photonic integrated circuits for the production of inplane and outofplane oam.
