Abstract
Recently, the possibility to realize a polymer laser diode has been investigated and it has been shown that optically pumped conjugated polymers generate stimulated emission in solution [1,2] and thin films [3-5]. In the latter case, it is necessary to build a microcavity around the polymer film in order to induce lasing. We demonstrate here that ultra thin (a few microns) single crystals of octithiophene (8T) naturally behave as luminescent optical resonators and are adapted to produce optically driven laser emission.
