Paper Abstract
In this paper, we demonstrate that the light extraction efficiency of an OLED is a strong function of the location of the
recombination zone and the ratio of the extracted mode to the substrate guided mode varies from 22% to 55%. The large
variation of the extraction efficiency in most OLEDs is the direct result of optical cavity effect present in the devices. In
addition, we show that the light intensity profile varies from a Lambertian shape to a non-Lambertian shape depending
of the device geometry.
