Abstract(in English) | Self-sustained pulsation semiconductor lasers which are less influenced by the optical feedback from surface of the optical disc, are under development. However, the feedback induced noise is not reduced when operating the pulsation lasers under some operating conditions. Furthermore, neither fluctuation of the pulsation nor a condition of generating the excess noise by the optical feedback has revealed yet. In this work, we show a generating condition for the feedback induced noise basing on changing the reflecting distance and feedback ratio for four different types of pulsation lasers. We classify the induced noise into 2 or 3 regions in the dependence on the reflecting point. Each region is characterized by fluctuation of the pulsation frequency and spectrum power. The characteristic at each region are explained in terms of the time difference of the feedback pulse from the self-sustained pulse. |
