Optically trapped room temperature polariton condensate in an organic semiconductor [PDF]
Nature Communications, 2022 The authors demonstrate on-the-fly reconfigurable optical trapping of organic polariton condensates which are delocalised over a macroscopic distance from the excitation region, holding great potential for future work on polaritonic lattice physics.

Low-threshold organic laser based on an oligofluorene truxene with low optical losses [PDF]
, 2009 A blue-emitting distributed feedback laser based on a star-shaped oligofluorene truxene molecule is presented. The gain, loss, refractive index, and (lack of) anisotropy are measured by amplified spontaneous emission and variable-angle ellipsometry.
