We investigated theoretically and experimentally the wavelength dependences of phase and group modal birefringence for the fundamental (E-11) and the higher order mode (E-31) 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 E-31 mode can be about 30% higher than of the fundamental mode. Additionally, we measured the modal birefringence of the both modes using scarming wavelength method. A comparatively good agreement between the calculation and experimental results was obtained confirming the validity of the theoretical analysis.
