Paper Abstract

A new spectral-domain interferometric technique used for measuring the group index of holey fibers over a wide wavelength range is presented. The technique utilizes an unbalanced Mach-Zehnder interferometer with a fiber under test of known length placed in one of the interferometer arms and the other arm with adjustable path length. First, the differential group index of the fiber is measured. Second, the fiber excitation is changed to guide light in the fiber cladding or the fiber is replaced by the reference sample of known thickness and known group dispersion to determine precisely the group index of the fiber at one specific wavelength. The group index as a function of wavelength is measured for two different holey fibers, one of them made of pure silica glass.
