Plasmonic continuous wave

Fig. 7. Pictorial representation of a Covalon ei(pi, C) traveling in chain A creating plasmon wave that affects another Covalon e, (p,, tj) in chain A to move toward (p2,t2). Since at t2 the plasmon wave changes its sign, the Covalon continues to move toward (p.3, C) and so on. It is not shown in the drawing but chain A now emits its own plasmon wave back to chain A thus creating a cooperative effect.

Structure A is the simplest structure formed by fusion sphcing a section of a coreless fiber to two pieces of continuous multimode fibers. In this sensor, different modes propagating in the multimode fiber expand to the surface of the coreless fiber in the central region and after reflection from the coreless fiber-environment boundary, get coupled back into the second multimode fiber fused to the coreless fiber. The evanescent waves at the coreless fiber-environment boundary excite plasmon resonance is the metallic nanoparticles formed on the surface of the coreless fiber section, as shown in Figure 3 A. This structure is not very effective for sensing purposes as there are a lot of...
