Paper Abstract

Theoretical calculations of the pulsing operation and the feeback induced noise are demonstrated. Dynamic equations of the photon number, the optical phase and the carrier density are formulated by counting the gain saturation effect as well as the optical injection for a laser having a saturable absorbing region to generate the self-sustained pulsation. Modulations on the pulsing operation due to the optical feedback are traced by performing the time integration of the equations. The feedback induced noise is also analyzed by adding the Langevin noise sources to these equations. Variations of the noise characteristics with the injection current level,the feedback distance and the feedback ratio are examined.
