    Abstract

    Optical vortex lattices (OVL) are gaining increased research attention owing to their unique features related to intensity and phase structure. Interference is a common method for generating an OVL. However, the topological charge (TC) carried in OVL is usually small and fixed and cannot be modulated, limiting its applications in many fields. This study applied phase multiplication to generate a high-order OVL to facilitate the arbitrary modulation of the TC. The generated high-order OVL exhibited the Talbot effect during transmission, and it transformed into a super-honeycomb lattice with specific fractional Talbot lengths. In addition, an orbital angular momentum was developed in the OVL. This has broad application prospects in optical micromanipulation. Furthermore, a method for generating super-honeycomb lattices was proposed. The findings of this study not only enhance understanding of the Talbot effect but also broaden the practical applications of OVL.
