Dichroism evaluation in high-birefringence fibres by means of crosstalk measurements

Abstract
A new method to evaluate dichroism and coupling parameters in highly birefringent fibres using crosstalk measurements is proposed. This technique is based on a model of coupled power equations taking into account the selective attenuation of polarised modes. Dichroism and coupling parameter values are precisely estimated through a wide set of measurements on a bow-tie fibre.
