Abstract :
The authors show that the frequency up-conversion of low-frequency noise present in drive oscillators can degrade the performance of microwave signals produced by a modelocked semiconductor laser. Experiments with low-frequency noise injection are used to demonstrate this effect. The results show also that the filtering effect of the external cavity resonances serves to reduce the sidebands of the up-converted low-frequency noise
