Beam propagation method and its application to integrated optic structures and optical fibers

Practical applications of integrated optics require understanding of light propagation in dielectric waveguides of various geometries and calls for elegant and quick methods of analysis. In this paper, we use beam propagation method to analyse some integrated optic waveguiding elements such as waveguide with bend and branching waveguide. The method is extended to cylindrical co-ordinates, so that structures with circular symmetry can be easily …
