We present a leaky thulium-doped photonic crystal fibre (PCF) design to down shift the thulium emission in the 1.7 - 1.8 μm band. The microstructured cladding structure manages confinement loss to counteract the thulium emission cross section. Thus, the fibre is considered as a distributed low pass filter along the fibre length. Computations on confinement loss show differential loss two orders of magnitude between 1.7 μm and 1.9 μm. We report on the fabrication and the linear characterization of the modelled fibre. A down shift around 1.75 μm of thulium fibre emission is experimentally demonstrated in single pass configuration.
