使用单个相移干涉仪测量了2.5倍频程波长范围(从375 nm到2100 nm)的光纤折射率分布。这个光谱范围比以前报道的多波长干涉仪大2倍以上，包括掺Er、Yb、Er：Yb和Tm掺杂光纤的泵浦和放大波段。该设备可以以空间分辨的方式测量材料色散，从而允许更准确地预测光纤的波导特性。测量波长可以定制，以优化材料色散、光学分辨率和干涉相位模糊的有利或有害影响。
Optical fiber refractive index profiles were measured across a 2.5 octave wavelength range (from 375 nm to 2100 nm) using a single phase-shifting interferometer. This spectral range is more than a factor of 2 larger than previously reported multi-wavelength interferometers, and includes the pump and amplification bands of Er-doped, Yb-doped, Er:Yb-doped, and Tm-doped fibers. The apparatus can measure the material dispersion in a spatially-resolved manner that permits more accurate prediction of the fiber’s waveguide properties. The measurement wavelength can be tailored to optimize the beneficial or deleterious effects of material dispersion, optical resolution, and interferometric phase ambiguities.
