Abstract :
This paper presents a systematic study of the effect of an extra current noise source added to the low-noise current injection source of a thermally stabilized vertical-cavity surface-emitting laser (VCSEL). An analytical study of a set of simple rate equations for a typical semiconductor laser is also carried out. On that basis, carrier noise is considered to be responsible for a change in the nonlinear gain saturation due to spatial effects.
