Cel The aim of the project is the experimental realization and characterization of ultralow threshold tuneable organic lasing structures. It has been demonstrated in the past, that under particular conditions, a cholesteric liquid crystal (CLC) material doped with a dye component (or a mixture of them) can constitute a lasing system. It has been also shown that the lasing threshold of this system inversely scales with the volume occupied by the active medium. Hence, the confinement of the dye-doped cholesteric material within nanosized cavities can result in an ultra-low or even zero-threshold lasing system.These cavities can be sculptured in a suitable photosensitive polymeric substrate by means of a highly precise and very short-pitched periodic light pattern obtained by holographic techniques and afterwards filled with the CLC-dye mixture. The cited techniques are very flexible and ensure a huge variability in the choice of the experimental parameters. This represents a research key point to reach a full optimization of the system and hence the success of the project.
