Electromagnetic Radiation from Organic Light-emitting Diodes
An analytical prototype model for the electromagnetic radiation emitted from a nanometric organic light-emitting diode device is presented and thoroughly investigated herein. The results are obtained via asymptotic evaluation of the resultant radiation integral in conjunction with coherence considerations, resulting in closed-form analytical expressions. For the sake of simplicity and clarity, we focus on a two-dimensional canonical configuration excited by impulsive (line) sources. The resultant expressions can be most effectively utilized by engineers for improved design, as they enable the calculation of the devices physical parameters, such as electrical to optical conversion efficiency and emission angular distribution, as a function of de-vice structure. It should be pointed out that the incorporation of both rigorous electromagnetic analysis and coherence effects is addressed in our report, to the best of our knowledge, for the first time. This results in a precise model capable of repeating and interpreting experimental and simulated data.
