AbstractThis paper has simulated the pump laser automatic signal control for erbium-doped fiber amplifier gain, noise figure, and output spectral power. Signal gain and noise figure are deeply studied in relation to laser pump power variations at operating pumping wavelengths of 980 nm and 1,480 nm for previous and proposed models. Similar to the study of the light signal to noise ratio, output power level and maximum Q factor are also simulated versus EDFA amplifier length at pumping power of 500 mW and different pumping wavelength by using the proposed model. The obtained results are better by using a pumping wavelength of 1,480 nm than a pumping wavelength of 980 nm. The optimum EDFA amplifier is 5 m, which gives better performance than other amplifier lengths.

And Performance

In this work, a single-stage C-band erbium-doped fiber amplifier (EDFA) has been constructed and characterized. Gain (G) and noise figure (NF) measurements collected for the C-band EDFA as a function of wavelength (1528.8 to 1562.3 nm) and laser pump powers are discussed. Further, the EDFA conversion efficiency (CE) as a function of laser pump powers is presented. Simplified mathematical expressions for the EDFA gain, NF, and CE are provided. The C-band EDFA signal gain remained flat in the spectral region 1539 to 1562 nm. Moreover, the C-band EDFA NF increased with wavelength and decreased with the 1480 nm laser pump powers. Additionally, the C-band EDFA maximum achieved conversion efficiency and signal gain is 22.64% at P1=19.49 mW and 22.6 dB at 1531.1 nm, respectively.
