Use of All-optical AGC EDFA for the Suppression of Signal Fluctuation in Free-Space Optical Transmission Systems

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We found that all-optical automatic gain-controlled (AGC) erbium-doped fiber amplifier (EDFA) could suppress the optical signal fluctuation effectively with high (>0 dBm) feedback amplified spontaneous emission power even with low input signal power into EDFA.
