Traveling Solutions of the Fuse Effect in Optical Fibers

In this paper, we reduce a partial differential equation that models the optical fiber fuse to an ordinary differential equation (ODE) using a traveling variable. This similarity reduction neglects the radiation loss term; however, the obtained fuse speeds are in good agreement with the ones obtained with the full propagation equation. The ODE results reveal the dependence of the fuse speed with the thermal parameters of silica and with the optical power density. We have also combined those results with experimental ones in order to adjust fiber absorption parameters.
