The Photonic Crystal Fibres (PCF) are microstructured waveguides currently developed in the frame of fibre telecommunications. This study is mainly focused on the improvement of dispersion property and wide spectral single-mode operating domain. Moreover, these fibres are highly birefringent and thus are able to maintain polarization. Consequently, in the astronomical context, this kind of fibre is a good candidate to design a fibre linked version of stellar interferometer. In this paper, we experimentally study the potential of these fibres taking advantage of the wide spectral single-mode operation. We propose an experimental setup acting as a two-beam interferometer using PCF. In a first time, the aim of this experiment is to measure fringes contrast at four different wavelengths (670 nm, 980nm, 1310 nm and 1543 nm) corresponding to four spectral band (R, I, J and H-band) with the same couple of PCF samples.
