基于特种光纤中超短脉冲非线性展宽的超连续谱(SC)源已成为生物医学成像、精密光谱学和超快光子学等广泛应用领域中不可缺少的工具。在最初竞相最大化其频谱带宽和覆盖范围之后，SC源的噪声特性最近已成为关注的焦点。商用SC源存在较大的脉冲间波动和相应较大的相对强度噪声(RIN)，严重限制了许多应用的灵敏度、精度或分辨率[1]。最近的工作表明，非线性光纤的色散工程对所产生的SC噪声特性起着重要的作用，因为全正常色散(ANDI)光纤抑制了噪声放大的非线性过程，这些过程通常主导了其反常泵浦的光纤的光谱展宽[2]，[3]。
Supercontinuum (SC) sources based on nonlinear spectral broadening of ultrashort pulses in specialty optical fibers have become an indispensable tool in a diverse range of application fields such as biomedical imaging, precision spectroscopy, and ultrafast photonics. After the initial race to maximize their spectral bandwidth and coverage, the noise properties of SC sources have recently shifted into focus. The large pulse-to-pulse fluctuations and correspondingly large relative intensity noise (RIN) present in commercial SC sources strongly limit the sensitivity, precision or resolution of many applications [1] . Recent work suggests that the dispersion engineering of the nonlinear fiber plays an important role for the resulting SC noise properties, as all-normal dispersion (ANDi) fibers suppress the noise-amplifying nonlinear processes that typically dominate the spectral broadening in their anomalously pumped counterparts [2] , [3] .
