Abstract

We report experimental and theoretical investigations with high-speed μ-OLEDs and demonstrate promising optical pulse responses as short as 400 ps using Alq3. These observations indicate that high-speed μ-OLEDs can be used for light communication in the GHz regime. The measurements are for in-house fabricated μ-OLEDs without cavity and size of 100 μm × 100 μm. With a validated model for an electrically pumped OLED, we simulate the generation of ultra-short optical pulses. The model includes Stoke-shifted reabsorption and field-enhanced Langevin recombination rate. For the Alq3 system we compare the results with the above-mentioned measurements. The good agreement between the measurement and the simulation is the basis for further study of the prospects for ultra-short dynamics and organic laser diode operation on the ps time scale.
