Abstract :
Herein, numerical and experimental results of the noise properties of slow light microwave photonic phase shifters based on coherent population oscillations in semiconductor optical amplifiers are presented. The main dependencies of the noise spectral density on key parameters accounting for phase shift tunability in this sort of devices are reported. Finally, discussions are given when considering the cascade of several phase shifting stages.
