The azimuthal quantum number (OAM) of light has received a lot of attention over the past two decades. OAM was first derived from the Laguerre-Gaussian (LG) beams and defined by the number of 2π phase shifts across the azimuthal direction of its wavefront [1].This parameter has been driven by interest in several …
