Simulación de la propagación de pulsos ópticos en guías de ondas micro estructuradas

Abstract

Se estudia la propagación de pulsos ópticos por el método de diferencias finitas en guías de onda estructuradas tipo ridge para aplicaciones en sistemas de transmisión de óptica en la región de 1,55 μm. Con la transformación de las ecuaciones de Maxwell de su forma continua a una formulación discreta para el sistema en estudio y con las condiciones de contorno apropiadas se implementó un algoritmo en Matlab que permitió visualizar el comportamiento del pulso al propagarse en la geometría del guía ridge

In this paper we study the propagation of optical pulses by the finite differences method in a ridge waveguides structured for applications in optical transmission systems in the region of 1.55 μm. With the transformation of Maxwell's equations its discrete formulation, for the system under study, and the appropriate boundary conditions was implemented an algorithm in Matlabthat enables to visualize the behavior of the pulse when it propagates in the geometry of the waveguide studied. Variations in simulation were made in the wavelength, width of the core and the refractive index materials with which the results obtained were consistent with those reported in the literature. This study allows proposing an appropriate geometry and materials for making waveguides for applications in optical communications systems.
