OLED-Pumped Organic Laser Diode

Abstract

A theoretical analysis is presented for a recently proposed high-speed µ-OLED optically pumped organic laser. We confirm that for this configuration, the laser threshold is reached at a lower current density than in the case of a direct-electrically pumped organic laser diode while generating pulses of order 15 ns duration. With a validated model for the electrically pumped organic light-emitting diode (OLED), we simulate the generation of light pulses. This light is fed into the organic laser section, where it optically pumps the emitting organic medium. The full model includes field-enhanced Langevin recombination in the OLED, Stoke-shifted reabsorption in both the OLED and organic laser, and an optical cavity in the latter. We numerically demonstrate 2 GHz modulation and conjecture the feasibility of ~0.025 Mb/s data transmission with this device.
