论文摘要
等离子体近场的剪裁是纳米光子领域的核心。对场分布的详细知识对于等离激元传感器，探测器，光伏，基于等离子的CICIT，纳米管剂，电流等离激元调节剂和原子设备的设计和制造至关重要。我们报告了近场观察和数值计算之间的完全定量比较，考虑到TM和TE极化的强度分布，这对于在所有这些领域构建设备所需的必要。我们介绍了表面等离子体极化子（spp）的近场扫描显微镜（NSOM），该结果是通过在金，纳米制动的透射光栅上线性极化照明而激发的。对红外光进行优化过程，用于将来在冷原子诱捕和等离子传感中应用。我们显示了SPP的堆积和传播的原位过程，并确认未将平面分量与光圈型NSOM探针耦合。
The tailoring of plasmonic near-fields is central to the field of nanophotonics. The detailed knowledge of the field distribution is crucial for a design and fabrication of plasmonic sensors, detectors, photovoltaics, plasmon-based cicuits, nanomanipulators, electrooptic plasmonic modulators and atomic devices. We report on a fully quantitative comparison between near field observation and numerical calculations, considering the intensity distribution for TM and TE polarisations, necessary for the construction of devices in all these areas. We present the near field scanning microscopy (NSOM) results of Surface Plasmon Polaritons (SPPs), excited by linearly polarized illumination on a gold, nanofabricated transmission grating. The optimization process is performed for infrared light, for future applications in cold atoms trapping and plasmonic sensing. We show the in situ processes of build up and propagation of SPPs and confirm that the out of plane component is not coupled to the aperture-type NSOM probe.
