This paper presents a method for generating and detecting spatiotemporal optical vortex (STOV) strings, which are wave packets containing multiple STOVs with customizable topological charge (TC) arrangements. The researchers demonstrate that a wave packet carrying 28 STOVs can be generated in the far field, with each STOV having a unique TC and position. The diffraction pattern of the wave packet can be used to simultaneously recognize the TC values and positions of all STOVs, enabling parallel detection of the STOV string. The study shows that STOV strings can be used for optical communication, as demonstrated by the successful transmission of an image using 16-STOV strings. The diffraction method is shown to be effective for detecting STOV strings with both ordered and random TC arrangements, and the results indicate that the method is robust for both short and long STOV strings. The paper also discusses the potential applications of STOV strings in optical communication, quantum information processing, and other fields. The study provides a framework for generating and detecting STOV strings, which could lead to more efficient optical communication systems. The results are supported by experimental data and simulations, and the paper includes supplementary materials that provide additional details on the experimental setup and results. The authors conclude that STOV strings have significant potential for use in optical communication and other applications, and that further research is needed to fully explore their capabilities.This paper presents a method for generating and detecting spatiotemporal optical vortex (STOV) strings, which are wave packets containing multiple STOVs with customizable topological charge (TC) arrangements.
