摘要
提出并验证了一种基于光纤参量环形镜(OPLM)和光纤光栅(FBG)的60GHz光毫米波副载波产生方案。理论上分析了OPLM的原理特性,发现可以利用OPLM同时完成光子微波信号的高次谐波产生和抽运滤波,直接获得光毫米波副载波信号。在实验验证中,从5GHz的基频信号出发,通过调制非线性和OPLM中的四波混频和滤波过程,完成高次谐波产生和抽运分离,成功得到60GHz的光毫米波副载波信号,表现出良好的性能。
Based on a fiber optical parametric loop mirror (OPLM) and a fiber Bragg grating (FBG), a scheme of 60 GHz optical millimeter-wave sub-carrier generation is analyzed and demonstrated. The conclusion indicates that OPLM can be used to achieve high-order harmonic and pump filter of photonic microwave signals at the same time, then optical millimeter-wave subcarrier can be obtained by leaving only the high harmonics. In the experimental demonstration, utilizing 5 GHz baseband signal, high-order harmonic generation and separation of the pump can be achieved by modulating the nonlinear and four-wave mixing and filtering in OPLM. Eventually, the required 60 GHz optical millimeter-wave sub-carrier signals can be realized successfully. Which shows good performance.
