Electromagnetic Mode Simulation on Optical Fiber Coupling With Transversal Misalignment

P. F. Gomes[1], R. G. e Souza[1], F. Beltrán-Mejía[2], J. L. G. Arango[3]
[1]Universidade Federal de Goiás, Jataí, GO, Brazil
[2]Universidade Estadual de Campinas, Campinas, SP, Brazil
[3]Universidad de Pamplona, Pamplona, Colômbia

We used COMSOL Multiphysics® software to calculate the mode distribution by numerically solving the wave equation in the fiber. We consider the transmission from the fiber 1 to the fiber 2. In the first case, the transmission was calculated as function of the wavelength of the propagated ... En savoir plus
