Based on Wiener-Khinchin theorem and Fourier transform, the coherence functions and the relevant parameters of various spectrums can be obtained from the simulation program. Through the analysis on the coherence properties of different spectrums, we also acquire the influence on the spectrum coherence of its characteristic parameters, such as the centre wavelength and the width. For the broadband sources used in the IFOG, the paper provides an effective calculation approach to acquire the accurate coherence functions and coherence parameters, which can be further used to analyze and optimize the SFS spectrums.

With ZnO nanorods hydrothermally synthesized on manually assembled arrays of optical fiber cores, 3D arrays of ZnO nanorod-based cylindrically hierarchical structures with nominal pitch 250 μm or 375 μm were constructed. Based on micrographs of scanning electron microscopy and image processing operators of MATLAB software, the 3D arrays of cylindrically hierarchical structures were quantitatively characterized. The values of the actual diameters, the actual pitches, and the parallelism errors suggest that the process capability of the manual assembling is sufficient and the quality of the 3D arrays of cylindrically hierarchical structures is acceptable. The values of the characteristic parameters such as roughness, skewness, kurtosis, correlation length, and power spectrum density show that the surface morphologies of the cylindrically hierarchical structures not only were affected significantly by Zn2+concentration of the growth solution but also were anisotropic due to different curvature radii of the optical fiber core at side and front view.

Pulse Broadening

The pulse broadening due to dispersion in optical fiber is studied by solving the nonlinear Schrödinger equation through the Fourier transform method. The expression of pulse width in terms of its root-mean-square and the pulse broadening factor of the Gauss-chirped pulse are given. Meanwhile, the influence of the propagating optical fiber distance on the pulse broadening is given. The influence of the chirped factor on the pulse broadening and the optical fiber dispersion on pulses with different widths are analyzed and discussed.
