Versatile Generation and Manipulation of 3D Optical Arrays

ABSTRACT This research explores the innovative generation of 3D arrays of optical beams and vortices using superposition of several distinct modified zone plate. Initial simulations successfully demonstrated the method's capability to create identical horizontal double spots at various separations, with transverse intensity profiles indicating uniform intensity levels. Subsequent investigations expanded the method's applications, producing diverse geometric configurations including square, diamond, hexagonal, and octagonal arrays. The study further showcased the ability to create complex 3D arrays of petal‐shaped optical beams with varying numbers of petals arranged in specific patterns. Moreover, the technique was adapted to generate arrays of optical vortices with different topological charges across multiple focal planes, illustrating significant versatility. Results, highlighted through detailed simulation outcomes and experimental validations, underscore the potential of these 3D optical structures in various fields such as optics, photonics, and advanced imaging systems.
