    Abstract

    The article comments on a recently reported OAM comb. The proposed approach relies on a simple azimuthal binary phase modulation scheme to transform a Gaussian beam into a structured light beam containing multiple OAM components with equal spacing and uniform power. It provides a convenient way to simultaneously tailor multiple OAM channels, with the potential to impact many fields, including optical information technology.

    Orbital angular momentum (OAM) of photons offers an additional degree of freedom by accessing the spatial structure of light beams. The most attractive property of OAM is its infinite number of eigen states. These OAM states constitute an infinite dimensional Hilbert space, contributing to a series of high-dimensional scenarios which could not be realized before.
