We investigate the phenomenon of slow-light propagation in planar photonic crystal waveguides and present a theoretical formalism and matching experiments to describe disorder-induced coherent scattering. The theory uses a coupled-mode approach to track multiple forward and backward reflections and a rigorous Green function technique to introduce the effect of disorder. Simulations based on this theory and experimental measurements for high-quality GaAs photonic crystal membranes are compared through transmission measurements and frequency-delay reflectometry. The excellent qualitative agreement between theory and experiment provides clear physical insight into naturally occurring light localization and multiple coherent-scattering phenomena in slow-light waveguides. Further, we briefly connect with related phenomena of absorption-induced losses in slow-light metamaterial waveguides.
