ABSTRACT:
A device for efficiently coupling electromagnetic radiation in the far-infrared and submillimeter spectral regions to surface plasmon waves comprises a prism constructed of a dielectric material, a first layer integrally formed on one face of the prism having an index of refraction which is less than the index of refraction of the prism, and a second overcoat layer formed integrally on the first layer and having an index of refraction which is greater than the index of refraction of the first layer.
