Download or read book Rib Waveguide Theory by the Spectral Index Method written by P. N. Robson and published by John Wiley & Sons. This book was released on 1990-11-30 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of semiconductor rib waveguides has, until now, relied upon very large finite difference or finite element calculations, sometimes using array processors. Here is a comprehensive introduction to the new spectral index method--a fast, accurate, reliable and stable method for finding waveguide propagation constants using Fourier methods. Shows researchers and professionals the field specific state-of-the-art problem-solving methods as well as wider applications in the many similar circumstances where both reliability and accuracy are considered mandatory.
