Abstract
We report on the laser modes in optically pumped solid-state lasers using a n electroluminescent organic semiconductor as the active medium. Mechanical ly flexible distributed-feedback lasers are fabricated by depositing a thin film of an active material onto a nano-patterned polyester substrate eithe r via spin-coating of a soluble ladder-type poly(p-phenylene) or via vacuum co-sublimation of small organic molecules. The different surface texture r esulting from the fabrication process causes different feedback mechanisms. In both lasers higher lateral modes give rise to a broadening of the laser spectra at higher pumping levels.
