We discover the formation of a temporal boundary soliton (TBS) in close proximity of a temporal boundary, moving in a nonlinear optical medium, upon high-intensity pulse collision with the boundary. We show that the emergent TBS is unstable to perturbations caused by the cross-phase modulation between the TBS and the other soliton products of the collision and that such instability triggers colossal intensity fluctuations of the reflected pulse ensemble with unprecedented magnitudes of the normalized autocorrelation function for an even weakly fluctuating input pulse.

时间边界孤子和极端超热光统计

我们发现在时间边界附近形成时间边界孤子 (TBS)，在与边界发生高强度脉冲碰撞时，在非线性光学介质中移动。我们表明，涌现的 TBS 对由 TBS 与碰撞的其他孤子产物之间的交叉相位调制引起的扰动不稳定，并且这种不稳定性触发反射脉冲系综的巨大强度波动，具有前所未有的归一化自相关函数幅度甚至微弱波动的输入脉冲。
