纳米结构中的等离子体代表了一种令人兴奋的新途径，特别是在亚波长尺度上有效地操纵光子。特别感兴趣的是杂化等离子体系统，其中等离子体元件之间的相互作用可以用于定制光学响应。在这里，我们展示了一个杂交等离子体波导系统表现出类似的电磁感应透明的行为，即，由耦合引起的等离子体共振的取消所产生的ultransarrow传输线宽度。
Plasmons in nanoscale structures represent an exciting new route toward efficient manipulation of photons, especially at subwavelength scales. Of particular interest are the hybridized plasmonic systems, in which the interaction among the plasmonic elements can be utilized to tailor the optical responses. Here we demonstrate a hybridized plasmonic-waveguide system exhibiting behavior similar to that of the electromagnetically induced transparency; namely, an ultranarrow transmission line width arising from a coupling-induced cancellation of the plasmonic resonance.
