Abstract

We present the results of theoretical and experimental analysis of waveguiding in a two-mode birefringent holey fiber in which the birefringence is induced by two large holes adjacent to the fiber core. First, using a full-vector finite-element method we modeled the wavelength dependence of the phase and group effective indices for the fundamental and higher-order linearly polarized (LP) modes in two orthogonal polarizations. Then we evaluated the wavelength dependence of the phase and group modal birefringences for both LP modes and the intermodal dispersion in two orthogonal polarizations as well. Second, we used different interferometric techniques, including time-domain and spectral-domain ones and a lateral force method, to measure in a broad spectral range the wavelength dependence of the phase and group modal birefringences for the fundamental and higher-order LP modes. Employing a white-light spectral interferometric method, we also measured the wavelength dependence of the intermodal dispersion for two orthogonal polarizations of the two LP modes. Furthermore, using an unbalanced Mach-Zehnder interferometer we measured the wavelength dependence of the relative group effective index for the fundamental mode.
