In a linear slow light system the delaying process is necessarily inducing distortion for fundamental reasons, strictly bounding the maximum delay-bandwidth product to unity. Slowing the light does not directly enhance light-matter interaction, but is a corollary of the intensity enhancement by multiple interferences.
