引入了一种新的品质因数（FOM），包括与受激布里渊散射（SBS）相关的输入泵浦功率限制，用于评估光纤的克尔非线性效率。新的FOM表示为gamma LeffPSBS（gamma是非线性参数，L-eff是有效长度，P-SBS是SBS阈值），而传统的FOM由gamma L-eff给出。使用新的FOM，我们对四种最先进的非线性光纤进行了效率比较：Bi 2 O3基非线性光纤、二氧化硅基多孔光纤、高度非线性色散位移光纤和传统色散位移光纤。由于Bi_2O_3玻璃的非线性性能优于石英玻璃，因此Bi_2O_3基非线性光纤具有最好的克尔非线性效率。(c)2005年，美国光学学会。
We introduce a new figure of merit (FOM) including the input pump power limit associated with stimulated Brillouin scattering (SBS) for evaluation of the Kerr nonlinearity efficiency of optical fibers. The new FOM is expressed as gamma LeffPSBS (gamma is a nonlinearity parameter, L-eff is effective length, and P-SBS is the SBS threshold), while the conventional FOM is given by gamma L-eff. Using the new FOM, we perform an efficiency comparison among four types of state-of-the-art nonlinear optical fiber: a Bi2O3-based nonlinear fiber, a silica-based holey fiber, a highly nonlinear dispersion-shifted fiber, and a conventional dispersion-shifted fiber. The Bi2O3-based nonlinear fiber is found to have the best Kerr nonlinearity efficiency owing to the superior nonlinear property of the Bi2O3 glass compared with that of the silica.
