The figures are as follows:

 

Fig. 3: Dynamically measured phase change of the compensated delay-line interferometer from 26 ℃ to 32 ℃ (black scatter points), and the 3rd order polynomial fitting (red line).

Fig. 4. Measured thermal sensitivity of T-SSMF (black, dashed), T-HCF (blue, solid), and the compensated delay-line (dash-dot, red) interferometers, measured from 25 to 60°C. The shown numbers refer to the slopes of the corresponding curves.

Fig. 5: Fig. 5. The dynamically measured (red line) and statically measured (black scatter points) thermal phase sensitivity of the compensated delay-line interferometer. Both show the zero thermal phase sensitivity crossing at a temperature of 28°C.

Fig. 6: Fig. 6. The measured (black scatter), fitted (2nd order polynomial fit, blue dash-dot) and calculated (red solid, Eq.(4)) relationship between the T-SSMF length and compensated delay-line interferometer zero thermal sensitivity  temperature when the T-HCF branch is kept 40 m.

Fig. 7. Calculated wavelength-dependent thermal sensitivity coefficient of T-SSMF and T-HCF.

Fig. 8. Calculated thermal sensitivity of the compensated delay-line interferometer as a function of wavelength with zero thermal sensitivity set to 1550 nm.
