我们展示了一种减少基于 SBS 的慢光系统失真的简单方法。失真的减少只是基于增益带宽的加宽和调整。然而，扩大的增益会减少可实现的分数延迟，而这无法通过更高的泵浦功率来补偿。在这里我们将证明这种补偿可以通过额外的损耗谱来完成。通过所提出的方法，高分数脉冲延迟的低失真是可能的。我们展示了我们的方法的理论和实验验证。对于分数延迟为 1 位的高斯脉冲，我们实现了约 23% 的失真减少。
We show a simple method to reduce the distortions in SBS based slow light systems. The distortion reduction is simply based on a broadening and adaptation of the gain bandwidth. However, a broadened gain reduces the achievable fractional delay which cannot be compensated by higher pump powers. Here we will show that this compensation can be done by additional loss spectra. With the presented method low distortions for high fractional pulse delays are possible. We show the theory and experimental verifications of our method. For Gaussian pulses with a fractional delay of 1 Bit we achieved a distortion reduction of around 23%.
