Embodiment 1
[0023] Such as figure 1 As shown, in this embodiment, a single row of metal pillars 2 is vertically arranged on the substrate 1. This metal pillar structure has obvious wavelength selectivity to the reflection of surface plasmons, forming a surface plasmon wavelength selective sex mirror. The metal pillars are composed of silver metal pillars with a radius of 200nm. The central projection points of a single row of silver metal pillars can be connected into a line segment, and the distance between every two adjacent silver metal pillars is 400nm. This surface plasmon wavelength selective device has good reflection characteristics. When a wide plane wave light source is perpendicular to the substrate, the far-field reflection angle-wavelength reflection spectrum generated is as follows: figure 2 shown. In particular, under the above incident conditions, the far-field reflection intensity at zero-degree angle varies with wavelength as image 3 As shown, there is an obvious de...
Embodiment 2
[0025] Such as Figure 4 As shown, in this embodiment, double rows of metal pillars 2 are vertically arranged on the substrate 1. This kind of metal pillar structure has obvious wavelength selectivity to the reflection of surface plasmons, forming a surface plasmon wavelength selective sex mirror. The metal pillars are composed of silver metal pillars with a radius of 200nm. The projection of each row of silver metal pillars can be connected into a line segment, and the distance between every two adjacent silver metal pillars in the same row is 800nm; between two rows of silver metal pillars The pitch is 400nm. This surface plasmon wavelength selective device has special reflection characteristics. When a wide approximate plane wave surface plasmon source is incident perpendicular to the connection line of metal pillars, the resulting reflection angle-wavelength far-field reflection spectrum is as follows: Figure 5 As shown, both the zero-order reflection intensity and the ...
Embodiment 3
[0027] Such as Figure 6 As shown, in this embodiment, 12 metal pillars are vertically arranged on the substrate, and the connection line of the central projection point is two concentric hexagons, forming a closed regular figure and forming a plasmonic nanoresonator . 12 silver metal pillars with a radius of 200nm form an inner and outer two-layer structure. The lines connecting the projection centers of the inner and outer silver metal pillars respectively form a regular hexagon. These two regular hexagons have the same center, and the inner layer The side length of the regular hexagon is 800 nm, and the side length of the regular hexagon in the outer layer is 1100 nm. This surface plasmon nano-resonator has good locality, and the surface plasmon resonates in the resonator to form multiple modes.
