Through a fully analytical model [Phys. Rev. B 78, 245108 (2008)], we investigate the impact of several disorder models on backscattering losses in photonic crystal waveguides. To evaluate their relative relevance, we compare the predictions with loss measurements. The comparison suggests that a long-range disorder at the scale of every hole has to be considered in disorder model, in addition to the more classical hole surface roughness.
