摘要
We report the modified and improved whispering gallery mode laser emission from a hollow polymer optical fiber doped with 1,4-Bis(2-methyl styryl) benzene (Bis-MSB), a high-quantum yield dye with a blue emission, with the introduction of an Ag nanoparticle-doped microring. In the presence of the Ag-doped microring, the laser emission was enhanced, and a reduction in the laser threshold from 40 to 15 mu J was attained, along with a small redshift in the emission spectrum. The quality factor of the microring embedded hollow polymer optical fiber was found to be 1.3 x 103. Moreover, the introduction of an Ag-doped microring inside the hollow polymer optical fiber helps enhance certain lasing modes. The observations open the way for the development of low-threshold polymer optical fiber lasers in the blue region.(c) 2023 Optica Publishing Group
