A method for the electromagnetic analysis of photonic crystal waveguides is described. It is tested against experimental transmission data obtained for AlGaAs slab-waveguide structures perforated by a two-dimensional hexagonal lattice. A good quantitative agreement is obtained for the band edge locations, for the ripples in the transmission windows, and more importantly, for the out-of-plane losses induced by the finite hole depth. The ultimate performance of the structure for deep etched holes is predicted.
