论文摘要
最近，通过光学折射率的空间定期调制实现了单光子的光谱操纵。在这里，我们将这种机制概括为巨大的颗粒，即通过激光引起的电势的空间调制来实现颗粒的加速度或减速。在光子集成芯片上，我们提出了通过激光驱动的分布式调制单元提出的MEV速度加速度。该机制也可以应用于原子捕获，该原子捕获有望将毫米级减速器捕获原子。时空调制方法是通用的，可以推广到其他系统，这可能在混合光子芯片和微观粒子操作中起重要作用。
Recently, the spectral manipulation of single photons has been achieved through spatial-temporal modulation of the optical refractive index. Here, we generalize this mechanism to massive particles, i.e. realizing the acceleration or deceleration of particles through the spatial-temporal modulation of potential induced by lasers. On a photonic integrated chip, we propose a MeV-magnitude acceleration by distributed modulation units driven by lasers. The mechanism could also be applied to atom trapping, which promises a millimeter-scale decelerator to trap atoms. The spatial-temporal modulation approach is universal and could be generalized to other systems, which may play a significant role in hybrid photonic chip and microscale particle manipulation.
