Roadmap on spatiotemporal light fields

Abstract Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents the holy grail human everlasting pursue ultra-fast information transmission and processing as well ultra-intense energy concentration extraction. It also holds key to unlock new extraordinary fundamental physical effects. Traditionally, spatiotemporal pulses are always treated spatiotemporally separable wave packet solution Maxwell’s equations. In past decade, however, more generalized forms nonseparable started emerge growing importance for their striking This roadmap intends highlight recent advances in creation control increasingly complex sculptured pulses, from states, diverse geometric topological structures, presenting a bird’s eye viewpoint on zoology fields outlook future trends open challenges.
