This book offers readers a comprehensive detailed analysis and treatment of optical waveguides fiber slab an essential component of ultrahigh bandwidth long medium and shorthaul telecommunication. The author describes an analysis scheme for optical waveguides that combines both geometricray optics and Maxwells equationsbased classical electrodynamics. This unique approach enables readers to develop an intuitive understanding of this topic starting with macro properties e.g. V parameter of an optical fiber and progressively refining the analysis to individual modes of propagation through an optical waveguide.ampnbsp An exhaustive set of diagrams highlight the key features of an optical waveguide property such as acceptance angle meridional and skew rays in an optical fiber or signal attenuation and dispersion in an optical waveguide.ampnbsp The author also provides a set of readytouse ANSI C executables for both Linux and Windows that enable the reader to e.g determine the allowed propagation modes even odd TETM of a graded step index optical fiber and a slab waveguide.Offers readers a singlesource reference to the analysis and design of optical waveguidesBegins with macrolevel analysis of the properties of optical waveguides and dives deeply into details in a stepbystep manner enabling readers to develop an intuitive understandingIncludes C language executables along with optical waveguide analysis and design examples to demonstrate their use in context.
