光镊使用激光捕获并移动空间中的微观粒子。在这里，我们展示了一个类似的控制超短光脉冲，但在时间。我们的实验涉及存储在由连续波“保持”激光束泵浦的无源光纤环中的时间腔孤子。通过保持光束的相位调制，将腔孤子捕获到特定的时隙中，并通过操纵相位分布来使其在时间上四处移动。我们报告连续和离散操作的皮秒光脉冲的时间位置，同时和独立地控制几个脉冲内的列车的能力。我们还研究了瞬态漂移动力学，并显示与理论预测完全一致。我们的研究展示了如何利用腔孤子独特的粒子特性来实现对光的前所未有的控制。这些结果可能对光学信息处理产生重大影响。
Optical tweezers use laser light to trap and move microscopic particles in space. Here we demonstrate a similar control over ultrashort light pulses, but in time. Our experiment involves temporal cavity solitons that are stored in a passive loop of optical fibre pumped by a continuous wave 'holding' laser beam. The cavity solitons are trapped into specific time slots through a phase modulation of the holding beam, and moved around in time by manipulating the phase profile. We report both continuous and discrete manipulations of the temporal positions of picosecond light pulses, with the ability to simultaneously and independently control several pulses within a train. We also study the transient drifting dynamics and show complete agreement with theoretical predictions. Our study demonstrates how the unique particle-like characteristics of cavity solitons can be leveraged to achieve unprecedented control over light. These results could have significant ramifications for optical information processing.
