Abstract

Having obtained the eigenvalue and the modal field by using the Ritz–Galerkin method, we quit the cladding‐field expression in the form of a Laguerre–Gaussian function and reconstruct it with a modified Bessel function. The accuracy of the cladding field is thus improved. We also show its application to the calculation of the coupling coefficient. © 2003 Wiley Periodicals, Inc.
