Abstract

Space-time wave packets -- a new class of pulsed optical beams in which the spatial and temporal degrees of freedom are inextricably intertwined -- provide a new platform for the study of structured light. Space-time wave packets can be designed to be propagation-invariant (diffraction-free and dispersion-free) and travel at arbitrary group velocities in free space and transparent dielectrics. I will discuss recent results obtained with space-time wave packets including the observation of anomalous refraction, tunable axial acceleration or deceleration, and novel Talbot effects observed in space-time rather than in space or time separately.
