摘要:

我们通过实验证明了远场光通过连接的纳米天线耦合到高度受限的等离子体间隙模式。等离子体隙模的激发取决于入射光束的偏振、位置和波长。在交叉偏振中进行的远场测量允许检测从间隙波导重新发射的极其微弱的信号,并且可以显著地增加信噪比。

英文摘要:

We experimentally demonstrate the coupling of far-field light to highly confined plasmonic gap modes via connected nanoantennas. The excitation of plasmonic gap modes is shown to depend on the polarization, position and wavelength of the incident beam. Far-field measurements performed in crossed polarization allow for the detection of extremely weak signals re-emitted from gap waveguides and can increase the signal-to-noise ratio dramatically.
