    Abstract

    We investigated theoretically and experimentally the wavelength dependences of phase and group modal birefringence for the fundamental (E11) and the higher order mode (E31) supported by index guiding highly birefringent photonic crystal fiber. The birefringence in the investigated structure was induced by asymmetrical cladding consisting of one row of cladding holes with a diameter lower than the other cladding holes. The numerical simulations carried out with use of the full-vector finite elements method show that the birefringence of the E31 mode can be about 30% higher than of the fundamental mode. Additionally, we measured the modal birefringence of the both modes using scanning wavelength method. A comparatively good agreement between the calculation and experimental results was obtained confirming the validity of the theoretical analysis.
