摘要
The burgeoning growth of structured light has opened up new possibilities for harnessing the spatiotemporal coupling effects in light.Optical spatiotemporal vortices,as a subset of spatiotemporal light,have emerged as a focal point of recent research,owing to their distinctive characteristics and vast range for application.This unique structured light will endow photons with a new degree of freedom,promising to revolutionize researchers’understanding of photonics.Conducting thorough research on optical spatiotemporal vortices will establish a solid foundation for the development of innovative physical mechanisms and advanced applications in photonics.
