摘要：
We have demonstrated both slow light in the absorption regime and fast; light in the gain regime of a 1.55 mu m quantum-dot semiconductor optical amplifier at room temperature. The theory with coherent population oscillations and four-wave mixing effects agrees well with the experimental results. We have observed a larger phase delay at the excited state than that at the ground state transition, likely due to the higher gain and smaller saturation power of the excited state.
