The impact of large-scale longitudinal optical power nonuniformities on the dynamics of a Fabry-Perot semiconductor laser is analyzed. New rate equations which incorporate this effect are derived. The effects of optical power nonuniformity are shown to be small compared to those of phenomenological gain compression at low frequencies, and insignificant at the relaxation oscillation frequency, except in the limit of low facet reflectivity.>
