摘要:

在光学厚金属板的亚波长孔的非寻常光传输中观察到表面等离子体激元(SPP)的干涉图样。结果表明,入射光的相位可以转移到表面等离子体。我们可以通过调制两束入射光之间的相对相位来控制SPP的相消干涉和相长干涉。利用稍有位移的马赫-曾德尔干涉仪,我们还观察到了由亮条纹和暗条纹组成的表面等离子体干涉图样。

英文摘要:

Interference patterns of surface plasmon polaritons(SPPs) are observed in the extraordinary optical transmission through subwavelength holes in optically thick metal plate. It is found that the phase of incident light can be transferred to SPPs. We can control the destructive and constructive interference of SPPs by modulating the relative phase between two incident beams. Using a slightly displaced Mach-Zehnder interferometer, we also observe a SPPs interference pattern composed of bright and dark stripes.
