3. Techniques for exciting surface plasmons at a planar metal-dielectric interface
In this section, we discuss the main configurations encountered for surface plasmon generation and consider the case of planar interfaces. The case of cylindrical interfaces is briefly discussed.
3.1 Prism coupling
As mentioned above, the most common configuration for generating surface plasmons is that shown in figure 5 , known as the Kretschmann prism. Here, light is injected towards a flat face coated with a nanometric metal layer. The angle of incidence θ is greater than the critical angle θ c so that the light is totally reflected at the interface. The reflected power is then detected using a photodiode....
