We consider the effect of orbital angular momentum (OAM) on localized waves in optical fibers using theory and numerical simulations, focusing on splash pulses and focus wave modes. For splash pulses, our results show that they may carry OAM only up to a certain maximal value. We also examine how one can optically excite these OAM-carrying modes, and discuss potential applications in communications, sensing, and signal filtering.

光纤中携带轨道角动量的局域波

我们使用理论和数值模拟来考虑轨道角动量 (OAM) 对光纤中局域波的影响，重点是飞溅脉冲和聚焦波模式。对于飞溅脉冲，我们的结果表明它们携带的 OAM 只能达到某个最大值。我们还研究了如何以光学方式激发这些携带 OAM 的模式，并讨论在通信、传感和信号过滤方面的潜在应用。
