Abstract
This paper demonstrated the near field light intensity measurement and two-dimension intensity profile for the guided modes based step/linear/spline index core profile shape with different core segments. The refractive index is designed versus radial position for one fiber, two fibers, and 10 fibers per cable. The fiber is designed with different shape profiles with 5 μm core radius, and the fiber refractive index axis ranges from 1.4 to 1.5. The two-dimension intensity profile, near field light intensity plot and with different shape profiles radial intensity profiles are demonstrated and measured for the guided modes of the fiber at different wavelength windows based on the three different designed fibers. Nonlinear propagation parameter, total power launched in fiber core, effective fiber area, and effective refractive index are studied with different shape profile structures versus the spectral operating wavelength based on the three different designed fiber structures.
