Abstract :
A theoretical investigation of the stability of laser diodes subject to optical feedback from short external cavities has been undertaken. Unstable (chaotic) behaviour was found to be restricted to islands in the feedback strength and cavity length phase plane in short cavities. A study has been made of the transition from isolated islands of unstable behaviour to that of one continuous unstable region. This transition occurs as the external cavity length is gradually increased and accounts for the phase insensitive behaviour seen in the long cavity limit
