Abstract
An optically pumped circular grating polymer laser (see Figure) is obtained using a nanostructured quartz substrate covered with a thin film of methyl -substituted ladder-type poly(p-phenylene) (MeLPPP). The second-order grati ng serves at the same time as a 2D feedback mechanism and as an output coup ler. Laser emission perpendicular to the substrate with a clear threshold b ehavior, an extremely narrow spectral width, and a highly directional beam is achieved.
