| In optical fibers there exists an optical birefringence induced by external factors and stress produced in technological processes. The induced birefringence makes difficult to apply optical fibers in heads of polarimetric sensors. It has been proposed to use a photonic crystal fiber working in an index guiding regime due to the small value of stress in a fiber core produced by internal and external factors. This article presents an expansion of our earlier investigations. The expansion consists of investigations concerning the influence of external magnetic field induction on the state of polarization of light in the function of an azimuth of the input linear polarization ϕ. On the basis of the resulting characteristics optimal working points of the tested fiber were determined. |
