Description:
The excel file contains all experimental data used for generating Fig.1, Fig.2, Fig.4, Fig.5, Fig.6, and Fig.7

The figures are as follows:

Fig. 1. (a) The refractive index difference (Δn) profile of APS-EDF3. The insets show the 2D profiles of the LP01 and LP11 modes at 980 nm pump wavelength. (b) The core composition distributions (P2O5, Al2O3, Er2O3) of APS-EDF3. The inset shows a microscope image of the fiber end face.

Fig. 2. Cross-section spectra of P-EDF, APS-EDF1, APS-EDF2, and APS-EDF3 (a: σa and σe spectra from 1400-1700 nm; b: σa, σe and σesa spectra from 1575-1640 n; σa: dashed lines; σe: solid lines; σesa: dash-dotted lines). (The arrow direction in (a) indicates the EDF with more AlPO4.)

Fig. 4. Gain and NF spectra from 1580-1620 nm of P-EDF, APS-EDF1, APS-EDF2, and APS-EDF3 at room temperature (~23 oC). The input signal power was -25 dBm.

Fig. 5. At 1600 nm, the gain and NF variations with the input signal power increasing from -40 to 0 dBm for APS-EDF1, APS-EDF2, and APS-EDF3 at room temperature (~23 oC).

Fig. 6. Gain and NF spectra of APS-EDF3 at different temperatures from -60 to 80 oC. The inset shows the gain and NF variations with the temperature at 1600 nm.

Fig. 7. Temperature-dependent gain (TDG) coefficient spectra of P-EDF, APS-EDF1, APS-EDF2, and APS-EDF3.
