Description du projet
FET - Open
The present project aims at achieving foundational research on a world prime: an Organic Electrically Pumped Laser. Our novel approach is based on the engineering of organic heterojunctions in field-effect devices. On the way to realising the main objective, intermediate results and milestones represent by themselves important sub-objectives: 1. Field-effect device with high electron and hole mobility for organic integrated circuits. 2. High brightness light-emitting organic semiconductor device. The strategy proposed to reach the ambitious goal focuses on solving the main difficulties, which are commonly faced when targeting this breakthrough: exciton quenching and photon losses. We take advantage of the know-how developed on ambipolar light-emitting field-effect devices with lateral charge injection to explore unprecedented routes towards the electrically pumped organic laser. This novel approach combines the use of high-mobility (field-effect) structures, n- and p-type materials, phosphorescent compounds, the engineering of materials in heterojunctions, as well as of advanced device and photonic technology. The project activity is expected to have a profound impact on IST-related technologies. Lasers are used daily in a variety of applications. Electrically pumped lasers based on organic semiconductors possess numerous advantages over III-V semiconductor lasers, the most important being the higher integration potential on arbitrary substrates (including glass, polymers and the backend of silicon CMOS), the lower cost and the wider spectral range of possible lasing emission. The realisation of an electrically pumped organic laser would be a breakthrough in both physics of lasers and organic opto-electronics. The research towards this goal is clearly a long-term one, and it contains a very significant risk.
