Resumen:
|
We report a change from sub- to superluminal propagation upon increasing the modulation frequency of an amplitude-modulated 1550?nm signal when propagating through highly doped erbium fibers pumped at 980?nm. We show that the interplay between the pump absorption and the pump-power broadening of the spectral hole induced by coherent population oscillations may drastically affect the fractional advancement or delay of the signal for the considered fibers.
