AbstractA detailed performance analysis of homodyne-based coherent detection in Free-space optics (FSO) with various optical amplifiers is presented in this paper. Using homodyne detection in FSO system, the effect of scintillation is mitigated. To further enhance the performance of FSO system, various optical amplifiers such as erbium-doped fibre amplifier, semiconductor optical amplifier, gain-controlled amplifier and black box model of amplifier can be employed in the system. Improvement in the system can be validated in terms of BER, Q-factor and eye diagram.

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.
