Abstract :
We present the full characterization of the beatnote of an erbium doped distributed feedback fiber laser (DFB-FL) operating on two orthogonally polarized eigenstates around 1.55 μm. The dual-frequency laser (DFL) in the free running regime generates a microwave signals around 1 GHz with a RIN lower than -115 dB/Hz over the range 50 kHz-10 MHz and a phase noise of -67 dBc/Hz at 10 kHz of the RF carrier. Up to 600 MHz tunability of the RF beatnote is obtained by mechanical stress applied to the cavity.
