Mode-coupling analysis of anisotropic polarization-maintaining fibers.
We analyze the coupling between the fundamental vector modal fields of two parallel polarization-maintaining fibers. An improved coupled-mode theory is employed, which also applies to anisotropic materials. Results for the array-mode-propagation constants are presented as a function of the relative tilt angle between the principal axes of the two fibers.
