Abstract: We present a simulation approach to estimate the effect of disorder induced backscattering in slow light photonic crystal line-defect waveguides. The backscattering leads to localization and thus limits the maximal length of such waveguides. Loss in passive waveguides in the localization regime reduces ripples in spectral transmission and group delay whereas gain increases these resonant multiple scattering effects.
