To modelize infinite photonic crystal fibre (PCF) with 2D-finite-geometry mode solver, it is necessary to use a perfectly matched layer (PML). We have performed a new type of PML design to simulate propagation in PCFs.

The results obtained with index-guiding PCFs are in very good agreement with previous theoretical published results. Our PML is quickly optimized. The link between MATLAB and FEMLAB offers the possibility to modelise realized profile to estimate loss before experimental results.
