Vectorial Finite Element Bpm Scheme Applied To Coupled Leaky Waveguide

In this paper, an efficient finite-element formulation for dielectric media with transverse anisotropy is applied to the analysis of polished-type optical fiber couplers. The method uses triangular elements in the discretization and perfectly matched layers are used as absorbing boundary. In this case we assume that two cores are curved in a parabolic shape, and between them a leaky waveguide with an index-matching liquid layer is included. The distance between cores is variable parameters. Due the inclusion of leaky waveguide the coupling distance reduces drastically. © 2005 IEEE.6468Cassedy, E.S., Cohn, M., On the existence of leaky waves due to line source above a grounded dielectric (1961) IRE Transactions on Microwave Theory Techniques, pp. 243-246. , MayHernández-Figueroa, H.E., Fernández, F.A., Lu, Y., Davies, J.B., Vectorial Finite Element Modelling of 2D leaky Waveguides (1995) IEEE Transactions on Magnetics, 31 (3), pp. 1710-1712. , MayObayya, S.S., Azizur Rahman, B.M., Grattan, K.T.V., El-Mikati, H.A., Full Vectorial Finite-Element-Based Imaginary Distance Beam Propagation Solution of Complex Modes in Optical Waveguides (2002) IEEE Journal of Lightwave Technology, 20 (6). , JuneIssa, N.A., Poladian, L., Vector Wave Expansion Method for Leaky Modes of Microstructured Optical Fibers (2003) IEEE Journal of Lightwave Technology, 21 (4). , Aprilda Silva, J.P., Brandão, M.L., Vectorial fnite-element BPM scheme applied to the analysis of optical-fiber couplers (2004) Microwave and Optical Technology Letters, 41 (4), pp. 204-206. , Mayda Silva, J.P., Hernández-Figueroa, H.E., Frasson, A.M.F., Vectorial finite-element BPM Analysis for transverse anisotropic (2005) Journal of Lightwave Technology, 21 (3), pp. 567-576. , FebruaryDa SILVA, J.P., Brandão, M.L., Enrique Hernádez, H., Figueroa. 2004 (2004) Vectorial Finite-Element BPM Analysis applied to Optical Fiber Coupler.
