Optical space-time wave packets having arbitrary group velocities in free space
Controlling the group velocity of light in free space has been limited to small deviations so far. Here, the authors present a method to control the spatio-temporal spectrum and allow arbitrary group velocities of a wave packet in free space both above and below the speed of light.
