We discuss how dynamic light stopping and pulse time reversal can be implemented in dispersive waveguides via indirect photonic transitions induced by moving refractive index fronts. The previous concepts of light stopping/time reversal either require complex local variation of the device’s refractive index or rely on the strict phase matching condition, which imposes limitations on the amount of manipulated information. Until now, only single pulses or continuous waves were manipulated experimentally. Our scheme is not limited by a strict phase matching condition and does not require local index variations, thus it can manipulate broadband signals in a single step process. Here, we present several numerically integrated results for pulse time reversal and stopping/storage via indirect front-induced transitions. The presented results are experimentally feasible using existing photonic waveguide technologies.

逆转脉冲时间并停止在折射率前

我们讨论了如何通过移动折射率前沿引起的间接光子跃迁在分散波导中实现动态光阑和脉冲时间反转。先前的光停止/时间反转概念要么要求设备折射率的局部复杂变化，要么依赖严格的相位匹配条件，这会限制操纵信息的数量。到目前为止，仅通过实验操作单个脉冲或连续波。我们的方案不受严格的相位匹配条件的限制，并且不需要局部指标变化，因此它可以在单个步骤中处理宽带信号。在这里，我们通过间接的前感应跃迁给出了脉冲时间反转和停止/存储的几个数值积分结果。
