Abstract

This article proposes automatic power control (APC)-erbium-doped fiber amplifier (EDFA)-based scintillation-suppressed photodetection in satellite optical communication (SOC). It is mainly based on the dynamic gain characteristic of APC-EDFA. In order to improve the performance, high pass filter (HPF) and Manchester on-off-keying (M-OOK) are introduced as supplemental methods. The proposed scheme is evaluated experimentally under various turbulence channel strengths. The experimental results show that the scintillation effect is suppressed using APC-EDFA with pump power reduction compared to gain saturation, and an approximate 5.83 dB signal-to-noise ratio improvement is obtained compared to adaptive threshold decision with instantaneous turbulence channel state information under a scintillation index of 0.2990.
