我们通过实验证明了等离子体纳米电路作为亚衍射定向耦合器工作，在λ (0) = 1550 nm处使用光学Yagi-Uda型天线从自由空间以高效率进行光激发。光学Yagi-Uda型天线设计为通道等离子体波导提供高效率（耦合45%，总发射60%），窄角指向性(
We experimentally demonstrate plasmonic nanocircuits operating as subdiffraction directional couplers optically excited with high efficiency from free-space using optical Yagi-Uda style antennas at lambda(0) = 1550 nm. The optical Yagi-Uda style antennas are designed to feed channel plasmon waveguides with high efficiency (45% in coupling, 60% total emission), narrow angular directivity (
