Abstract :
This paper studies the optical angular momentum in periodic arrays. This work shows a gray-scale representation of the phase cross-section of a periodic array of optical vortices. The phase gradient gives rise to transverse linear momentum, which in turn leads to a nonvanishing angular momentum density.
