Qiwen Zhan (USST) Topology with Spatiotemporally Sculptured Light

With the rapid advances in laser technology, optical fields with various topological features have attracted increasing attentions. In this talk I will review recently developed techniques that allows us to directly sculpt optical fields in the spatial and spatiotemporal domains. These spatiotemporal sculpturing techniques are employed to produce optical fields with various topological features. Wavepackets with these complicated topological structures exhibit many unique properties and may find important applications when interact with matters, opening tremendous potential opportunities for sculptured complex spatiotemporal wavepackets.
