Vertical-cavity organic lasers with distributed-feedback structures based on active Bragg reflectors.
Optically pumped organic thin-film lasers were fabricated by stacking top and bottom Bragg reflectors with an inner-cavity active layer between the reflectors. We observed single-longitudinal-mode laser operation at 555 nm by doping pyrromethene-567 dye into all the stacked layers. The threshold of the laser was 30% less than that of a laser operated with nondoped Bragg reflectors, which was in good agreement with calculations.
