Optical Domain Microwave Amplifier
Based on a pure photonic feedback loop, this system can generate a photonic microwave signal without optical–electrical–optical conversion or any electrical microwave devices. A semiconductor optical amplifier implements the functions of microwave envelope detection and feedback. An optical-domain wideband microwave amplification system which takes advantage of the large bandwidth capacity of optical devices to amplify optically carried microwave signals is proposed. A partly carrier-suppressed optically carried microwave signal is generated and amplified by erbium-doped fiber amplifier (EDFA) in this scheme. In this paper, we review our recent works about a microwave photonic repeater, self-interference.
