Abstract

Erbium-doped optical fiber can serve as either a saturable absorber or (when pumped) as a saturable amplifier, leading to slow or fast light propagation respectively. A variety of exotic propagation effects are observed in this system.

We demonstrate pump-power-tunable slow and superluminal pulse propagation at room temperature in an erbium-doped fiber amplifier. Signal pulses at 1550 nm were sent through an EDF with various pump intensities, obtaining signal group velocities as slow as 19,000 m/s and as fast as -16,000 m/s.

Signal Evolution of Slow and Fast Light in Erbium Doped Fiber

Hao Wang, Chunguang Zhang

Recently, researches about the controllable group velocity of light propagation had made many progresses. And several experiments had demonstrated the signal evolution of slow and fast light. In this letter, the authors described a simple experiment for the tracing of light signals in an erbium-doped optical fiber at the optical communication wavelength firstly. We have, directly, observed the evolution of slow and fast signals with different waveforms that travel in an erbium-doped fiber amplifier. Through tracing the signal evolution, when slow light (Vg<;<;c) or fast light (Vg<;0) was got in it, we concluded that asymmetrical absorption and amplification on the periodical signal could account for the generation of slow and fast light in an erbium-doped fiber amplifier easily.

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)
