We present a framework for the information theoretic analysis of slow-light devices. We employ a model in which the device input is a binary-valued data sequence and the device output is considered within a window of finite duration. We use the mutual information between these two quantities to measure information content. This approach enables the information theoretic definitions of delay and throughput. We use our new framework to analyze a delay device based on stimulated Brillouin scattering (SBS) and find good agreement with previous SBS delay bounds.
