Generation of a polygonal perfect optical vortex array by optical pen

Abstract

The perfect optical vortex (POV) has generated a large number of applications in classical to quantum physics because its diameter is independent of its topological charge (TC). Previous reported POVs still show a lack of controllable size, shape, and amplitude, which may hinder their applications. In this paper, a combined phase is used to create complex polygonal perfect optical vortex (PPOV) arrays. The size, number, position, shape, and amplitude of the PPOVs in the array are controllable, where the shape can be an arbitrary symmetric polygon. We investigate the transmission characteristics of the PPOV arrays. The generation of PPOV arrays further provides more flexibility in optical micro-manipulation, quantum entanglement, optical communication, and other fields.
