fibre optique à saut d'indiceThis worksheet presents a demonstration of Maple software's capabilities in the resolution of differential equations governing the propagation of an electromagnetic wave in a step-index optical fiber with a core radius of the order of magnitude of the incident radiation wavelength. It also presents the two and three dimensions graphical functionalities given by Maple which allows :
i) To access directly to the eigenvalue equation solutions.
ii) To check easily the continuity conditions of the electric E and magnetic H tangent components at the core-cladding boundary.
iii) To show in the three dimensions space the E and H vector fields.
iv) To show in the fiber transverse plane the light intensity distribution.
