用于单发射极偏振分析的耦合金属球近场亚波长局域化

Sub-wavelength localization of near-fields in coupled metallic spheres for single emitter polarization analysis

Po-Nan Li, Hsiu-Hao Tsao, Jer-Shing Huang, Chen-Bin Huang

摘要:

我们用数值方法证明了由耦合到等离子体纳米团簇的单个发射体的偏振态决定的选择性近场局域化。七个金纳米球被仔细排列,使得单个发射器的多达十个偏振态,包括线性、圆形和椭圆偏振,可以通过四个间隙中的不同场定位来区分。将偏振状态转换为场空间定位的能力可以应用于单发射极偏振分析。

英文摘要:

We numerically demonstrate selective near-field localization determined by the polarization state of a single emitter coupled to plasmonic nano-cluster. Seven gold nanospheres are carefully arranged such that up to ten polarization states of the single emitter, including linear, circular, and elliptical polarizations, can be distinguished via the distinct field localization in four gaps. The ability to transform polarization state into field spatial localization may find application for single emitter polarization analysis.
