Abstract
We apply the Finite-Difference Time-Domain algorithm to the problem of calculating modal loss in microstructured optical fibers. We use periodic boundary conditions in the longitudinal direction to isolate a mode that decays through transverse perfectly-matched layer boundaries. The loss coefficient is extracted by a direct monitoring of the energy enclosed in the simulation domain. Predictions of the method are compared to results from beam propagation and multipole approaches, and finally the tool is applied to fibers containing elliptical air holes.
