Abstract： An Eu-chelate-doped step-index polymer optical fiber (POF) is fabricated. Based on Judd-Ofelt (J-O) theory, the J-O parameters are calculated to be Ω2 = 16.93 x 10-20cm2, Ω4 = 1.36 x 10-20cm2, Ω6 = 6.75 x 10-20cm2 from the emission spectrum of Eu(DBM)3Phen-doped polymethyl methacrylate (PMMA). The J-O parameters have been used to calculate the total radiative transition rate (555.78 s-1) and radiative lifetime (1799μs) of the 5D0 exciting state. The stimulated emission cross-sections σij and the fluorescence branch ratios β for the 5D0 → 7FJ’ transitions are also evaluated. Analysis reveals that Eu(DBM)3Phen-doped PMMA is promising for use in rare-earth-doped polymer optical fiber devices.
