In this paper, we discuss the relations between the
spatially-distributed traveling wave, Lang-Kobayashi, and a new multi-mode
delay differential equation models for Fabry-Perot type semiconductor diode
lasers with an external optical feedback. All these models govern the
dynamics of the slowly varying complex amplitudes of the optical fields and
carrier density. To compare the models, we calculate the cavity modes
determined by the threshold carrier density and optical frequency of the
steady states in all three models. These calculations show that the
Lang-Kobayashi type model is in good agreement with the traveling wave model
only for the small feedback regimes, whereas newly derived multi-mode delay
differential equation model remains correct even at moderate and large
optical feedback regimes.
