Paper Abstract

Surface electromagnetic waves (SEW) are the normal modes of the EM radiation coupled to the optically active excitations of solids near the surface (also called surface polaritons). Optical guided waves used in integrated optics are one of the classes of SEW modes that appear in a layered geometry. We have investigated the dispersion and attenuation of SEW in the far infrared by means of inelastic scattering of light. All the expected modes in a single interface geometry (surface of a bulk) and a double interface geometry (film on a substrate) have been found, including the guided waves in thin slabs. These SEW modes occur near the infrared active optical phonon frequencies in semiconductors such as GaP and GaAs, and their behavior can be controlled by doping, roughening of the surface and an ex-ternal magnetic field. This review will focus on the character of these waves and suggest possible use in device applications.
