Abstract :
Saturated optical amplifiers in amplification and conversion schemes are used for suppression of turbulence noise in FSO links with high scintillation index. The PDF of logic-one and logic-zero levels are measured and compared with those of systems using the erbium doped fiber amplifier (EDFA) and semi-conductor optical amplifier (SOA). The proposed receiver structure using saturated optical amplifiers causes a significant reduction in scintillation index and as a result, a reduction of BER up to three orders of magnitude is observed
