Bright Ring Lattice Generated by Nesting Spiral-Pinhole-Arrays Plate

Abstract A nesting spiral-pinhole-arrays plate (NSP) is designed to produce bright ring lattice (BRL) formed by the superposition of two different orbital angular momentum (OAM) modes. The OAM modes of the BRL can be manipulated by the propagation distance and the spiral arrays of the NSP. We have studied the influences of rotating NSP on the BRL, and found that the rotational angle and direction of the BRL are not consistent with the results of the NSP.
