Abstract
A novel method for the systematic derivation of analytical approximations o f the fundamental-mode dispersion equation and field distribution of graded -index planar waveguides with uniform cladding is presented. The method is based on a Stevenson-Pade approach, recently introduced by the authors for the numerical analysis of graded-index optical fibers. A number of examples are presented in order to illustrate the power and accuracy of the method. (C) 2000 John Wiley & Sons, Inc.
