摘要

本文从理论上研究了具有一定面反射的半导体光放大器(SOA)的慢光和快光效应。用理论模型解释了引起相干居群振荡的SFL现象。研究了电流调制频率、电流值、线宽增强系数、面反射率以及调制电流的相对相位对SOA中相位延迟的影响。结果表明，SFL效应可以通过调制频率、电流值和相对相位来控制。最后，研究表明，SFL延迟的大小可以通过改变线宽增强因子以及SOA的面反射率来调整。

Numerical analysis of slow and fast light effect in semiconductor optical amplifier with certain facet reflection

In this paper, the slow and fast light (SFL) effects of the semiconductor optical amplifier (SOA) having certain facet reflections are theoretically investigated. The theoretical model is used to account for the SFL phenomenon causing the coherent population oscillation. The influence of the current modulation frequency, the value of the current, the linewidth enhancement factor, facet reflectivity as well as the relative phase of the modulated current on the phase delay in the SOA are studied. It is demonstrated that the SFL effect could be controlled by the modulation frequency, the value and relative phase of the current. Finally, it is shown that the magnitude of the SFL delay could be tuned by a change in the linewidth enhancement factor as well as the facet reflectivity of the SOA.
