Slow and fast light effects induced by interference with a control light field

Year: 2024

Type: article

Abstract: The group velocity of light is governed by the dispersive properties of the optical material. Controlling these properties has led to concepts such as fast and slow light. In a vacuum, the group velocity of light is equal to c, excluding a priori the possibility of controlling the propagation time of a light pulse. Here, we prove that to some extent, this limitation can be circumvented by exhibiting a specific class of periodic light pulses that can be advanced or delayed by simple linear interference with a monochromatic light field. We show that such pulses are easily generated in a recirculating frequency shifting loop, and we experimentally demonstrate the possibility of advancing or delaying these pulses by times exceeding the nanosecond.
