Tóm tắt

In this work, we reported an organic dye-doped polymer-coated optical fiber optofluidic laser (FOFL) that supports whispering gallery mode (WGM) laser emission. The dye-doped polymer was coated on the outer surface of single-mode fibers (SMFs) using a simple method to fabricate a uniform and consistent solid gain film. By using coated fibers as optical microcavities for lasers, a low lasing threshold of about 0.65 μJ/mm
