Circularly symmetric modal interferometers: Equalization wavelength and equivalent step determination for matched-cladding fibers

Abstract An LP01-LP02 modal interferometer fabricated from a standard matched-cladding telecommunication fiber is studied in the visible wavelength range. Its spectral response in the vicinity of the LP01/LP02 equalization wavelength is used to characterize the fiber by the determination of an equivalent step index profile.
