摘要:

本文基于相干布居振荡理论研究了半导体光放大器中的慢光和快光传输。通过调制注入电流来迫使粒子数振荡,我们可以修改光信号的延迟或提前。具体地说,研究表明,光信号与偏置电流调制的相对相位可以用作将光传播从延迟改变为提前的旋钮。此外,我们还分析了考虑腔效应后调制电流对垂直腔面发射激光器慢光特性的影响。它示出的调制的深度的变化允许调谐的结构共振,这反过来又产生增强的延迟。

英文摘要:

We present a theoretical study of the slow and fast light propagation in semiconductor optical amplifiers based on coherent population oscillations. By modulating the injection current to force the population oscillations we can modify the delay or advancement of light signals. Specifically, it is shown that the relative phase of the optical signal to the bias current modulations can be used as a knob for changing light propagation from delay to advancement. In addition, we analyze the effect of the modulation current for slow light in vertical cavity surface emission lasers (VCSELs) by taking into account the cavity effects. It is shown that the change of the depth of the modulation allows to tune the structural resonance, which in turn produces an enhancement of the delay.
