Far field calculations and experimental characterization of nanostructured OLEDs

We present far field calculations for nanostructured organic light emitting diodes (OLEDs) and compare these to experimental results. OLEDs with a nanostructured indium tin oxide (ITO) anode were fabricated and characterized. Corresponding two-dimensional far field calculations are carried out via two-dimensional finite difference time-domain code (2-D FDTD) with integrated 2-D far-field projection. Furthermore, spherical three-dimensional (3-D) far field calculations are obtained by an efficient multipole-based near-to-far field transformation from three-dimensional FDTD data.
