Descrição: Direct structuring of photocrosslinkable polyspirobifluorene copolymers by holographic lithography to yield insoluble, organic, distributed feedback (DFB) lasers with thresholds as low as 2 µJ cm−2 is reported (see figure). These DFB lasers (X‐LEP layer in figure) are embedded in the first optimized, multilayered slab‐waveguide organic light‐emitting diode with good luminance efficiency of ∼6 cd A−1 and concomitant low laser thresholds. The effect of electrical excitation on the optically pumped laser is investigated for the first time.
