Analysis of the tapered waveguide / A. Belghoraf 

Public ISBD Titre : Analysis of the tapered waveguide Type de document : texte imprimé Auteurs : A. Belghoraf, Auteur ; R. L. Beurle, Directeur de thèse Editeur : Nottingham : University of Nottingham Année de publication : 1984 Importance : 110 f. Présentation : ill. Format : 27 cm. Note générale : Thèse de Doctorat : Électronique : Angleterre, University of Nottingham : 1984 Bibliogr. f. 130 - 132. Annexe f. 111 - 129 Langues : Anglais (eng) Mots-clés : Tapered  waveguide  problems Plane  wave  spectral  analysis Intrinsic  mode  theory Parabolic  equation  method Index. décimale : D003484 Résumé : This thesis describes analytical and numerical investigations of tapered waveguide problems, for intergrated optics applications. A plane wave spectral analysis, models the propagation process of the tapered waveguide and introduces the concept of an Intrinsic spectral Integral, which turns out to be in good agreement with calculation in terms of Adiabatic modes. This allows us to extend the Intrinsic mode concept beyond the singularity where the Adiabatic mode concept breaks down. In this sense, the implementation of the resulting spectral formulation, for the case of homogeneous media, contains all information pertinent to the modal propagation mechanism, inside and outside the tapered waveguide; before and after the singularity caused by cut off of the Adiabatic mode. The thesis is mainly concerned with implementing the Intrinsic mode theory as a numerical computational tool. In this respect, very good agreement is demonstrated between this model and calculations performed numerically using the parabolic equation method. On the other hand, the new model contains far greater physical and analytical possibilities than previous methods. Analysis of the tapered waveguide [texte imprimé] / A. Belghoraf, Auteur ; R. L.
