Abstract

The predictor–corrector method is used for the numerical integration of Maxwell’s equations for radially inhomogeneous fiber problems. Its accuracy and efficiency compare favorably with the Runge-Kutta and collocation methods used previously. Its practical application is illustrated by its use to study the effects on the propagation characteristics produced by a central dip and a valley between the core and cladding in the index profile of a radially inhomogeneous fiber, normally having ^a parabolic core and a finite cladding. The departures of these propagation characteristics from those of the regular fiber with a parabolic index are pointed out.
