We present a novel approach for the computation of electromagnetic wave propagation in Photonic Crystal (PC) waveguides. The approach uses a Generalized Scattering Matrix method together with a basis of localized photonic Wannier functions. These photonic Wannier functions contain all the relevant information of the underlying crystal. The method allows efficient investigation of finite-sized PC samples, various defect and waveguiding structures. In particular, we consider the effects of disorder on the transmission characteristics of these structures.
