Optical fiber is rapidly becoming the transmission medium of choice for new telecommunication systems. For a true lightwave network to evolve, however, optical control devices such as optical switches and multiplexer-demultiplexers will be essential.

Surface waves and guided waves
1956Although surface waves and guided waves may exist under a wide variety of conditions our main concern will be those generated in the earth by earthquakes or explosions. These waves are of interest to seismologists not only because they form the most prominent features of seismograms but also for their usefulness in determining the structure of the ...

Wave Harmonics and Guided Waves
2014Solutions of the homogeneous Helmholtz equation are referred to as wave harmonics. In this chapter, we will discuss the solution of this equation in rectangular, cylindrical and spherical coordinate systems. They are respectively called plane waves, cylindrical waves and spherical waves.

Use a one-dimension theory based on the normal to a plane wave to evaluate the propagation of light in a dielectric layer. If the ray strikes the walls of the guide it must meet the condition for total reflection. The theory, called the zigzag model, is not a “pure” geometric theory because we use the properties of interference and of phase change upon

Journal of Applied Physics, 1948
The paper is devoted to a discussion of the properties of electromagnetic waves propagating with a velocity W <c. Boundary conditions are obtained for structures with very narrow slots, either closed or open, and a general method of solution of the wave equations is discussed.

Nonlinear guided waves have important applications in ultrafast communication systems. These lead to new problems in electromagnetic theory which present interesting and challenging opprtunities for the development of the subject. This short review outlines the new problems which result from this development with reference to some selected but ...
