Collective stimulated emission processes in conjugated polymers makes these materials potential candidates for laser applications. The fabrication of a low-cost flexible distributed feedback laser (see Figure and also the cover) by spin-coating a conjugated polymer onto a specially structured, flexible plastic substrate is reported. Single-mode laser emission in the blue-green spectral region has been achieved.
