我们描述了一种在允许的脉冲失真约束下最大化慢光脉冲延迟的方法。我们表明，在更大数量的物理变量上进行优化可以增加失真约束的延迟。我们通过比较使用单个洛伦兹增益线和使用一对紧密间隔增益线可实现的最佳慢光脉冲延迟来演示这些概念。我们预测，与最佳单线延迟相比，使用增益双极体的失真管理可以提供大约2倍的慢光脉冲延迟。光纤中布里渊增益的实验结果证实了我们的理论预测。
We describe a methodology to maximize slow-light pulse delay subject to a constraint on the allowable pulse distortion. We show that optimizing over a larger number of physical variables can increase the distortion-constrained delay. We demonstrate these concepts by comparing the optimum slow-light pulse delay achievable using a single Lorentzian gain line with that achievable using a pair of closely-spaced gain lines. We predict that distortion management using a gain doublet can provide approximately a factor of 2 increase in slow-light pulse delay as compared with the optimum single-line delay. Experimental results employing Brillouin gain in optical fiber confirm our theoretical predictions.
