Abstract
We present the results of broadband dispersion measurement of a two-mode birefringent holey fiber (BHF). First, a spectral interferometric technique employing an unbalanced Mach-Zehnder interferometer with the fiber in the test arm is used for measuring the wavelength dependence of the group effective index of the fundamental mode supported by the fiber. Second, a spectral interferometric technique employing a tandem configuration of a Michelson interferometer and the BHF under test is used for measuring the group modal birefringence dispersion for two lowest-order linearly polarized (LP) modes supported by the BHF. The data measured over a broad spectral range are fitted to polynomials to obtain the dispersion of the phase modal birefringence for both LP modes. We reveal that the results are in agreement with a general model of birefringence in air-silica BHFs.
