(2022) (INVITED) Bi-doped optical fibers and fiber amplifiers Optical Materials: X Description: The excel file contains all experimental data used for generating Fig.2 to Fig.12, Fig.15 and Fig.19. The figures are as follows: Fig. 2 Main pump wavelengths and luminescence bands of major Bi-doped silica-based fibers within different glass hosts that are commonly used in Bi-doped fiber amplifiers. Fig. 3 Absorption spectrum of BASF, BPSF and BGSF samples. The inset shows the detailed absorption from 800 nm to 1600 nm. Fig. 4 Unsaturable loss of BASF, BPSF and BGSF samples measured at their pump wavelengths (BASF - 1047 nm, 1120 nm; BPSF - 1240 nm; BGSF - 1270 nm, 1310 nm, 1432 nm). The inset shows a typical UL measurement of a BPSF sample. Fig. 5 Fluorescence spectra of BASF sample. Fig. 6 Fluorescence spectra of BPSF sample. Fig. 7 Fluorescence spectra of BGSF sample. Fig. 8 Refractive index profile and Bi2O3 and P2O5 distribution of BPSF-1. Fig. 9 Saturation fluorescence measurement of BPSF sample. The inset shows the obtained saturation pump power Psat. Fig. 10 Absorption cross-sections measured by saturation fluorescence method for BPSF-1, 2 and 3 at pump wavelengths of 1200 nm, 1267 nm and 1310 nm. The scatter represents the measured absorption cross-section data by the saturation fluorescence method. The dashed lines are the absorption cross-section spectrum predicted using Gaussian curve fitting. Fig. 11 Emission cross-section spectrum calculated by FL equation for BPSF sample. Fig. 12 Maximum gain and 3-dB bandwidth with the corresponding peak gain wavelength of Bi-doped fiber amplifiers operating in the O-band (1260-1360 nm). Fig. 15 Maximum gain and 3-dB bandwidth with the corresponding peak gain wavelength of Bi-doped fiber amplifiers operating in the wavelength band from 1300-1500 nm. Fig. 19 Gain and NF spectrum of E+S-band BDFA for a signal power of -10 dBm.
