A nearly diffraction limited surface emitting conjugated polymer laser

Summary form only given. Recent approaches towards low threshold solid state lasers are based on two-dimensional photonic bandstructures (2D-PBS). Stimulated emission and optically pumped lasing action has been observed for a variety of organic electroluminescent materials like e.g. conjugated polymers. Due to their high optical gain and the ease of fabrication organic solid state laser materials are well suited as active media in photonic crystal lasers. We have fabricated a surface emitting 2D-PBS laser utilizing a substrate which is nanopatterned through a UV-embossing process.
