The figures are as follows:


Fig. 2:	
Fig.2a	                                Simulated frequency noise spectrum when considering self-injection locking noise (SIL) and thermal noise (TRN).
Fig.2b                                      Lorentzian linewidth as function of the HCF-FP length.

Fig. 4:
Fig.4a	                                Transmitted signal through the HCF-FP measured over 50 MHz.
Fig.4b                                      Detail of transmission of single peak.

Fig.6: 
Fig.6a 	                                Frequency error as a function of time achieved here and its comparison with the stability of a laser locked to an SMF delay line placed in a vacuum 
Fig.6b                                      Allan deviation calculated from the data shown in (a)  and its comparison to measurements reported by manufacturers of commercially-available narrow-linewidth lasers, including OE waves, which is also based on self-injection locking. 

Fig. 7                                       Measured frequency noise via strong self-injection ratio of -15 dB, together with free-running laser and measurement noise floor. 
            
Fig. 8                                       Measured frequency noise with different self-injection ratios. 

Fig. 9                                       Comparison of the measured and simulated frequency noise for injection ratio of -15 dB (green) and -30 dB (red).

Fig. 10                                     RIN of the free running and SIL. Shot noise expected for 0 dBm power output is also shown.
