Tracing rays through graded-index media: a new method
TL;DR: A new method for tracing rays through graded-index media by transforming the ray equation into a convenient form and solving the resulting equation using a standard numerical technique is presented.
Journal ArticleDOI
Numerical analysis of planar optical waveguides using matrix approach
TL;DR: In this article, a simple matrix method for obtaining propagation characteristics, including losses for various modes of an arbitrarily graded planar waveguide structure which may have media of complex refractive indices, is presented.
Journal ArticleDOI
Analysis of rectangular-core dielectric waveguides: an accurate perturbation approach
TL;DR: The exact solution of the scalar-wave equation for a rectangular-core waveguide structure is reported and a perturbation analysis for evaluating accurately the propagation characteristics of practical integrated-optical structures is developed.
