Abstract

Simple models predict that pulses propagate backwards through a material with a negative group velocity. We find that the peak of the pulse does propagate backwards, even though no energy propagates in that direction.

The nature of pulse propagation through a material with a negative value of the group velocity has been mysterious, as simple models seem to predict that pulses will propagate "backward" through such a material. Using an erbium-doped optical fiber and measuring the time evolution of the pulse intensity at many points within the fiber, we demonstrate that the peak of the pulse does propagate backward inside the fiber, even though the energy flow is always in the forward direction.

We exploit the versatility of erbium doped fiber to study pulse propagation in situations of positive and negative group velocities. We also study effects resulting from the use of shaped pulses containing broad spectral components.

We study propagation of light pulses and modulation in an Er-doped fiber in the regimes of anomalously slow and superluminal group velocities. The pulses experience either delay or advancement depending on the pump power.

We report a change in the propagation regime (subluminal-superluminal) of light pulses in a pumped erbium doped fiber. We explain this behavior as a propagation effect. A pulse-width separator based on this effect is proposed.

We proposed and demonstrated the propagation of slow/fast light in erbium-doped fiber through gain cross modulation. We observed the ultraslow light with a group velocity of 6.1×10-3 c and the superluminal propagation with a negative group velocity of -5.1 ×10-4c. (2 pages)
