摘要

提出了一种用于B5G/6G通信的基于双环光电振荡器(OEO)的微波光子变频系统，并进行了实验验证。该方案通过双环OEO产生相位噪声低、侧模抑制比高的本振信号。通过改变双极化双驱动马赫-曾德尔调制器(DP-DDMZM)的偏置电压，可以实现上下转换状态的切换。在实验中，当LO信号的频率为20.0025 GHz时，将6 GHz的中频信号上变频为26.0025 GHz的射频信号。同时，使用相同的LO信号，将14ghz的RF信号下变频为6ghz的IF信号。该方案能够满足B5G/6G无线通信系统对更高工作频带的要求。

Microwave Photonic Frequency Conversion System Based on a Dual-loop Optoelectronic Oscillator for B5G/6G Communication

A microwave photonic frequency conversion system based on a dual-loop optoelectronic oscillator (OEO) for B5G/6G communication is proposed and experimentally demonstrated. In this scheme, a local oscillation (LO) signal with low phase noise and a high side-mode suppression ratio is generated by a dual-loop OEO. The up- and down-conversion state can be switched by changing the bias voltages of the dual-polarization dual-drive Mach-Zehnder modulator (DP-DDMZM). In the experiment, the intermediate frequency (IF) signal at 6 GHz is up-converted to the radio frequency (RF) signal at 26.0025 GHz when the LO signal is with a frequency of 20.0025 GHz. Meanwhile, the RF signal at 14 GHz is downconverted to the IF signal at 6 GHz by using the same LO signal. The proposed scheme can meet the requirement of the B5G/6G wireless communication system with the higher operation band.
