摘要

Signal instability in conventional dual-loop optoelectronic oscillators (OEOs) poses a significant challenge to their practical implementation. To address this issue, this paper proposes a novel OEO architecture based on a polarization-nonreciprocal dual-loop structure. The proposed configuration employs a Faraday rotating mirror (FRM) in the optical path, which inherently offers resilience against environmental perturbations. This design ensures a fixed polarization rotation per circulation, effectively eliminating polarization-induced drift. Experimental results demonstrate that the proposed OEO achieves a phase noise of -101.8 dBc/Hz at a 10 kHz offset. Moreover, it exhibits output power stability 4.5 times higher than that of conventional designs, along with a 22.1 dB improvement in the sideband rejection ratio. This work presents a simple and effective approach for stable, high-performance microwave signal generation.
