微波光子链路基于光纤的低损耗、大带宽、抗电磁干扰等优点而得到广泛地应用。一方面,分析了激光器的输出功率与电光调制器的偏置电压对微波光链路增益的影响,通过优化系统参数提高链路增益;另一方面,基于理论分析与仿真,结合实际器件的性能指标,提出了实现高增益链路的具体实施方案。 Microwave photonic link is widely used based on optical fiber’s low loss, large bandwidth, anti-electromagnetic interference and other advantages. The effects of the intensity of the laser, the half wave voltage and the bias voltage of electro-optic modulator on the gain of the microwave link are analyzed. Then, based on the theoretical analysis and simulation, combined with the performance index of practical devices, the implementation scheme of high gain link is proposed.
