Abstract

We present novel numerical techniques for the simulation of the light outcoupling from state of the art organic light-emitting diodes (OLED). For the spatial discretization we use the finite element method which we apply in the frequency domain. To account for the large horizontal extension of the OLED we apply a recently proposed approach based on the Floquet transform which allows to restrict the calculations to the unit cell of a (quasi) periodic structure. Optically thick layers are efficiently treated by a plane wave expansion which we combine with the Finite Element Method by the domain decomposition method. We benchmark the new simulation tools for highly efficient state of the art OLED light extraction structures.
