OLED-pumped organic laser

Abstract

We report a numerical investigation of the recently proposed (Nature 621, 2023, 746) high-speed μ-OLED optically pumped organic laser and confirm that in this configuration the threshold for quasi-CW lasing is much easier reached than in case of a direct-electrically pumped organic laser diode. With a new model for the electrically biased OLED, we simulate the generation of pulsed and quasi-CW light. This light is fed into the organic laser where it optically pumps the emitting organic medium The model is voltage-driven and includes field-enhanced Langevin recombination in the OLED, Stoke-shifted reabsorption in both the OLED and organic laser, with an optical cavity in the latter. We numerically demonstrate 3.5 kA/cm2 laser threshold current density, 1 GHz modulation and conjecture the capability of Gb/s data transmission with this device.
