ANALYSIS OF THE REFRACTING LEAKY MODES IN D-SHAPED OPTICAL FIBERS

Antônio R. Sapienza, Marcelo F. Guimarães

Abstract


An analytical solution for the refracting leaky modes of a waveguide with circular core and large circular cladding neighbouring a dielectric halfspace is presented in this article. This model is applied to D-shaped fibers and the results confirm what is verified experimentally: the x-polarization, normal to the surface, irradiates more than the y-polarization, parallel to the surface. The analysis of a structure with the cladding constituted by air is done. Graphics of the behavior of the real and imaginary parts of the effective index as a function of the spatial frequency are obtained for both polarizations as well as the graphics of the power densities, calculated for the fundamental and the first superior modes.
