Abstract : Recent advances in diode technology have paved the way for a new family of devices using guided electromagnetic wave propagation in pn junctions. These devices appear useful in the infrared spectrum as sources, modulators, or optical circuit elements. An understanding of the wave propagation is essential to device design and realization. This report deals with the general characteristics of this propagation, and works out the propagation characteristics of the guided modes existing in the diode space charge layer. The problem of guided electromagnetic wave modes in a three-layer dielectric sandwich is discussed. General solutions are found in terms of the dielectric constants, central layer width, and frequency. The solutions are valid for media with small loss tangents. These results are then applied to the electromagnetic wave modes guided along the depletion layer of a pn junction. (Author)
