Abstract
The customization of optical vortices with controllable structures is of fundamental importance for promoting various applications such as materials processing, optical communication, and optical tweezers. Here, a model of coherent beam combining (CBC) architecture was proposed to customize the exotic light beams array with controllable structures. The simulated results revealed that the optical vortex lattice (OVL) with multi-modes can be generated in the far field, and a proof-of-concept experiment was carried out for further verification. The experiment results were in a high degree of fidelity with the simulated results, indicating that the controllable structures could be generated efficiently by using the CBC architecture. The phenomenon of generated hollow beam having no orbital angular momentum (OAM) and the OVL copying can be observed. Furthermore, the phase detection experimental results verified the OAM states, the topological charge (TC) could be modulated from −2 to + 2. This work may present a new understanding of generating and manipulating the structured light fields.
