“…So far, the dispersion of the orthogonally polarized fundamental modes and the dispersion of the second-order even LP 11 mode near cut-off have been analysed theoretically and experimentally. Time domain low-coherence interferometry and spectral domain white-light interferometry with channelled spectrum detection have been used for measuring dispersion characteristics of birefringent optical fibres [7][8][9][10][11][12][13][14][15][16]. Time domain interferometry has been used to measure the polarization-mode dispersion [7] and dispersion of modal birefringence in highly birefringent optical fibres [8][9][10].…”

We present the results of measurement and modelling of the birefringence dispersion in elliptical-core fibres (ECFs). The measurement is performed over a broad wavelength range (e.g. 450–1450 nm) by two spectral interferometric techniques. First, a technique employing a tandem configuration of a Michelson interferometer and an ECF under test is used for a broad spectral range measurement of the group modal birefringence for two spatial modes supported by the fibre. Second, a method with a lateral point-like force acting on the fibre and based on spectral interferometry is used for measuring the phase modal birefringence at one wavelength for the fundamental mode only. The measured value is combined with the dispersion of the group modal birefringence to obtain the phase modal birefringence over a broad wavelength range. We also modelled the dispersion characteristics taking into account contributions of both the elliptical shape of the core and the residual thermal stress. The dispersion characteristics measured for the three ECFs show very good agreement with the results of numerical modelling.
