Green‐emitting polymer lasers based one‐ and two‐dimensional distributed feedback (DFB) mechanisms are achieved through direct writing by interference ablation. The polymer semiconductor material is removed at the bright fringes as the spin‐coated polymer film is exposed to the interference pattern of a single UV laser pulse, producing the 1D DFB structures of the light‐emitting polymer. Multiple exposing processes enable the fabrication of 2D structures, proving this to be a simple and flexible technique for the realization of a variety of organic laser schemes.
