摘要	High threshold is the main obstacle to achieving direct electrically pumped polymer lasers. In this paper, high-performance blue light material, polyfluorene(PFO) is used as a laser gain medium. A planar optical microcavity with appropriate structure is designed based on cavity quantum electrodynamics principle. The self-absorption of active layer material is further reduced by lowing the thickness of polymer layer. Optical microcavity is constructed by DBRs with two different material system. The extra optical loss is cut down in the preparation process of top DBR, and the optical resonator with low loss and high Q value is finally obtained. An optically pumped low threshold polymer laser with a peak wavelength of 443 nm and a threshold of only 30 mW/cm2 is realized by effectively controlling the spontaneous emission and stimulated emission characteristics of PFO. 2019, Science Press.
