Abstract :
Quantum dash mode-locked laser are very simple sources to generate a low linewidth tone over an optical signal. Such a devices has been used to generate a tone at its third harmonic, at 30 GHz and integrated into an optical self-injection loop in order to get a low phase noise oscillator. A phase noise as low as -105 dBc/Hz at an offset frequency of 100 kHz has been obtained with such a source.
