Abstract :
The voltage-current characteristic of the absorber of a twin section laser diode is investigation as a function of the gain section current. For selfpulsation to occur the absorber must be operated within a specific region of the voltage-current characteristics. This region only exists for absorber voltage-current characteristics which contain an S-shaped negative resistance.
