我们报道了中心波长为1070 nm的类噪声脉冲(NLP)在远离零色散点的正常色散区通过一条长长的标准单模光纤(~100米)传输产生宽带超连续谱。理论模拟表明，SC产生的物理机制是由光纤中的非线性效应引起的。级联拉曼散射导致较长波长区域的光谱显着展宽，而克尔效应导致SC产生的光谱平滑。SC具有低阈值(43 NJ)和1050-1250 nm的平坦光谱。
We report generation of broadband supercontinuum (SC) by noise-like pulses (NLPs) with a central wavelength of 1070 nm propagating through a long piece of standard single-mode fibers (~100 meters) in normal dispersion region far from the zero-dispersion point. Theoretical simulations indicate that the physical mechanism of SC generation is due to nonlinear effects in fibers. The cascaded Raman scattering is responsible for significant spectral broadening in the longer wavelength regions whereas the Kerr effect results in smoothing of SC generated spectrum. The SC exhibits low threshold (43 nJ) and a flat spectrum over 1050-1250 nm.
