迈向纳米尺度上的完全时空控制
Toward Full Spatio-Temporal Control on the Nanoscale
摘要：
介绍了一种在纳米尺度上实现全相干控制的方法。它是基于时空调制的表面等离子体激元（SPP）场在厚边缘的一个边缘的。SPP波包传播到这个尖锐的边缘，这个尖锐的边缘被压缩和电磁集中在一个nanofocus，形成一个超短脉冲的本地字段。该脉冲的一维空间轮廓和时间波形是完全相干控制的。
英文摘要：
We introduce an approach to implement full coherent control on nanometer length scales. It is based on spatio-temporal modulation of the surface plasmon polariton (SPP) fields at the thick edge of a nanowedge. The SPP wavepackets propagating toward the sharp edge of this nanowedge are compressed and adiabatically concentrated at a nanofocus, forming an ultrashort pulse of local fields. The one-dimensional spatial profile and temporal waveform of this pulse are completely coherently controlled.
