Abstract

Many authors implemented numerical techniques to analyze the propagation of optical signals in dielectric waveguides, with purpose of eliminating the spurious modes [1]-[5]. The Finite Element method has been used with excellent results for the propagation constant [6]-[15]. The Finite Difference technique for rectangular dielectric structures added substantial contributions for these problems [16]-[18]. Both of them, analyzing the case of loss inside the guide region [19]-[21] Most of these analyses assume the piecewisecontinuity of the dielectric constant. In this paper, that condition is applied to the curl-curl equation to derive an H-Jeld Finite Element Method to obtain the propagation constant. Our numerical results agree with the other methods one. The advantage of this formulation is that it does not require the use ofthe perturbation technique to solve for loss or gain in waveguide and include the continuity of the Hz and Ez components at the dielectric boundary interface.
