Electrically driven organic laser using integrated OLED pumping.

ABSTRACT: Organic semiconductors are carbon-based materials that combine optoelectronic properties with simple fabrication and the scope for tuning by changing their chemical structure^1-3. They have been successfully used to make organic light-emitting diodes^2,4,5 (OLEDs, now widely found in mobile phone displays and televisions), solar cells¹, transistors⁶ and sensors⁷. However, making electrically driven organic semiconductor lasers is very challenging^8,9. It is difficult because organic semiconductors typically support only low current densities, suffer substantial absorption from injected charges and triplets, and have additional losses due to contacts^10,11. In short, injecting charges into the gain medium leads to into
