摘要：
The guided and leaky modes of the optical wave guides (fibers) are analyzed by the finite-element method (FEM) with the integral boundary, conditions. The initial equations are reduced to the algebraic general eigenvalue problem, which is solved by the Arnoldi algorithm. The mode dispersion characteristics, fields, and cutoff frequencies are calculated for several waveguide structures, including flat and multilayer fibers with different shapes of cross sections.
