Temperature-Dependent Saturation Characteristics of Injection Seeded Fabry–PÉrot Laser Diodes/Reflective Optical Amplifiers

In this paper, the temperature dependence of the gain and saturation power of injection seeded Fabry-Perot laser diodes/reflective semiconductor optical amplifiers are analyzed theoretically and experimentally. For a constant gain, the saturation power increases with the ambient temperature. This dependency explains the observed variation in relative intensity noise versus injection power, as a function of temperature.
