Paper Abstract

The slow light is always at the cost of the signal distortion when the periodic rectangular signal propagates in Erbium-doped fiber (EDF), which is confirmed by the implemented simulations and measurements. A new definition of Fundamental Harmonic Fractional Delay (FHFD) is proposed based on the fundamental harmonic phase delay with the consideration of signal distortion to evaluate the slow light effect. The influences of signal power, modulation depth and duty ratio on slow light effect are studied, and the relationship between Fundamental Harmonic Fractional Delay (FHFD) and Total Harmonic Distortion (THD) is given.
