In this work, we present the fabrication of chalcogenide photonic crystal fibres (PCFs) with a solid core for three different glass composition containing a variety of chalcogens. We show that the Stack and Draw technique currently used for silica PCFs can be problematic in the case of chalcogenides glasses. We prove that excess losses are related to the interface between the capillaries. We also present correct PCF design enables a significant improvement of final fibre losses. We obtained a lowest attenuation of 3dB/m at 1.55μm, of 4.5dB/m at 3.39μm and 6dB/m at 9,3μm.
