(2020) Ultra-broadband Bismuth-Doped Fiber Amplifier Covering a 115-nm Bandwidth in the O and E Bands Journal of Lightwave Technology Description: The excel file contains all experimental data used for generating Fig.1 and Fig.3 to Fig.9 The figures are as follows: Fig. 1 Absorption spectrum of BPSF-1 (the inset represents the refractive index profile of BPSF-1). Fig. 3 Gain and NF spectrum of BPSF-1 from 1345 nm–1460 nm for input signal powers of -10 dBm and -23 dBm at room temperature, where the inset shows the signal and ASE spectrum for a -23 dBm input signal from which the in-band OSNR is derived (fiber length = 220 m, total launched pump power = 850 mW). Fig. 4 Gain and NF characteristics of BPSF-1 as a function of the pump power at a signal wavelength of 1420 nm for signal powers of -10 dBm and -23 dBm at room temperature (fiber length = 220 m). Fig. 5 Gain and NF characteristics of BPSF-1 as a function of the input signal power at a signal wavelength of 1420 nm at room temperature (fiber length = 220 m, total launched pump power = 850 mW). Fig. 6 (a)(b) Temperature dependent gain and NF characteristics of BPSF-1 in the temperature range from -40 °C to +60 °C for (a) -10 dBm and (b) -23 dBm input signal powers (fiber length = 220 m, total launched pump power = 850 mW). Fig. 7 Gain and NF characteristics of BPSF-1 from -40 °C to +60 °C at 1420 nm for input signal powers of -10 dBm and -23 dBm, where the slope of dashed line represents the TDG coefficient. (fiber length = 220 m, total launched pump power = 850 mW; the inset represents gain and NF characteristics of BPSF-1 from -40 °C to +60 °C at 1360 nm). Fig. 8 Gain and NF spectrum of BPSF-1, BPSF-2, BPSF-3 from 1350 nm–1460 nm for an input signal power of -23 dBm at room temperature (BPSF-1: fiber length = 220 m, total launched pump power = 850 mW; BPSF-2: fiber length = 212 m, total launched pump power = 844 mW; BPSF-3: fiber length = 210 m, total launched pump power = 859 mW). Fig. 9 (a)(b)(c) Two Gaussian peaks curve fitted at ~1360 nm and ~1420 nm based on the gain spectra for -23 dBm input signal of BPSF-1, BPSF-2 and BPSF-3. (BPSF-1: fiber length = 220 m, total launched pump power = 850 mW; BPSF-2: fiber length = 212 mvv, total launched pump power = 844 mW; BPSF-3: fiber length = 210 m, total launched pump power = 859 mW).
