dc.description.abstract | We investigate the incoherent diffusion of excitons in thin films (5.1±0.1nm thick) of a highly absorbing J-aggregated cyanine dye material (106 cm-1 absorption constant) as the excitonic component of a polariton microcavity. Under high-intensity pulsed laser excitation, the J-aggregated molecular films exhibit significant exciton-exciton annihilation, indicating a large exciton diffusion radius of more than 100 nm. When the material is strongly coupled to a cavity, the polaritonic structure also shows exciton-exciton annihilation, which is a competing process against the establishment of a threshold population of polaritons needed for polariton lasing. This study suggests that exciton-exciton annihilation is a loss process which can significantly increase the lasing threshold in polariton microcavities. © 2010 The American Physical Society. | en_US |
