Abstract

We show that nanophotonics can provide a compact and versatile platform to generate controllable space-time light. We will present three of our recent works: 1. Creating structured 3D linear space-time light bullets in free space using nonlocal metasurface. 2. Creating guided light bullets in a multimode waveguide using photonic interband transitions. 3. Creating spatiotemporal optical vortices with arbitrarily oriented OAM using photonic crystal slabs. Our works illustrate the significant opportunities in creating nontrivial space-time correlations with nanophotonic devices.
