超快光场驱动的电子纳米电路的前景刺激了阿秒纳米物理这一新的研究领域的发展。推进这一新领域的一个基本先决条件是能够表征光与纳米结构相互作用的光学近场，具有子周期分辨率。在这里，我们实验证明阿秒近场检索的锥形金纳米线。通过与惰性气体实验和轨迹模拟结果的比较，可以提取出激光激发产生的纳米锥近场的光谱响应。 来自纳米尺度结构的光电发射提供了一条通往超快光场驱动电子纳米电路的途径。在这里，作者使用阿秒条纹光谱学在锥形金纳米线附近的近场的纳米级表征。
The promise of ultrafast light-field-driven electronic nanocircuits has stimulated the development of the new research field of attosecond nanophysics. An essential prerequisite for advancing this new area is the ability to characterize optical near fields from light interaction with nanostructures, with sub-cycle resolution. Here we experimentally demonstrate attosecond near-field retrieval for a tapered gold nanowire. By comparison of the results to those obtained from noble gas experiments and trajectory simulations, the spectral response of the nanotaper near field arising from laser excitation can be extracted. Photoemission from nanometre-scale structures offer a route toward ultrafast light-field-driven electronic nanocircuits. Here, the authors use attosecond streaking spectroscopy for nanoscale characterization of near-fields in the vicinity of tapered gold nanowires.
