We demonstrate experimentally the manipulation of Airy surface plasmon beams in a linear potential. For this purpose, we fabricate dielectric-loaded plasmonic structures with a graded refractive index by negative-tone gray-scale electron beam lithography. Using such carefully engineered potentials, we show that the bending of an Airy surface plasmon beam can be fully reversed by the potential.
我们通过实验演示了线性势中 Airy 表面等离激元光束的操控。为此，我们采用负电子束光刻技术制作了具有渐变折射率的介质加载等离子体结构。利用这种精心设计的势，我们表明 Airy 表面等离激元光束的弯曲可以完全被势反转。
