We demonstrate that interference of absorption pathways can be used to control resonant coupling of light to guided modes in a manner analogous to quantum coherent control or electronically induced transparency. We illustrate the control of resonant coupling that interference affords using a plasmonic test system where tuning the phase of a grating is sufficient to vary the transfer of energy into the surface plasmon polariton by a factor of over 10(6). We show that such a structure could function as a one-way coupler, and present a simple explanation for the underlying physics.
我们证明，吸收路径的干涉可用于以类似于量子相干控制或电诱导透明的方式来控制光与导模的共振耦合。我们使用一个等离子体测试系统来说明干涉所提供的共振耦合控制，在该系统中，调节光栅的相位足以使进入表面等离子体激元的能量转移变化超过10⁶倍。我们表明，这样的结构可以用作单向耦合器，并对其 underlying 物理原理给出了一个简单解释。 （注：原文中“underlying”直接保留英文未翻译完整，推测可能是文档录入有误，若按正确理解翻译应该是“潜在的”之类意思，这里按原文呈现的英文翻译）
