Influence of the excitation area on the thresholds of organic second-order distributed feedback lasers
It is shown that the optical pump power (or energy) density thresholds required to obtain lasing from organic second-order distributed feedback lasers, increase when the excitation area (A) is smaller than a certain value (A crit).

Film thickness and grating depth variation in organic second-order distributed feedback lasers
We report on the preparation and characterization, under optical pump, of second-order one-dimensional distributed feedback (DFB) lasers based on polystyrene films doped with a perylenediimide derivative, as active media.
