Herein, we verify that a Raman/EDFA hybrid amplifier can improve the stability of fiber-optic time and frequency synchronization systems compared to the Er3+-doped fiber amplifier (EDFA), owing to its higher gain and lower noise figure (NF) performan

We design and manufacture a narrow-band photodetector that can perform high-gain detection of 2.4 GHz RF signals and strongly suppress noise and harmonics, which is proved to be better applied to optical fiber RF transfer.
