摘　　要：通信技术的飞速发展对带宽提出了更高的需求,移动通信向毫米波等更高频段发展,w波段(74-110 GHz)的宽频谱可以满足对高流量的需求,为人们对w波段系统的研究提供了巨大的推动力。本文理论提出并仿真了一种使用三角波信号作为射频信号驱动双驱动马赫增德尔调制器(DDMZM)产生高阶边带,用高非线性光纤(HNLF)产生四波混频效应(FWM)进一步提高倍频数的生成90 GHz毫米波的30倍频光生毫米波产生方案。仿真结果表明,该实验方案可以使用3 GHz的射频信号生成90 GHz的光生毫米波信号,且搭载2.5 Gbit/s的NRZ信号传输20 km后,眼图清晰信号质量良好。另外分析了HNLF长度以及输入HNLF的光信号强度对FWM的影响,得到能使HNLF产生最佳±15阶边带的条件,进而进一步优化整个系统。The rapid development of communication technology puts forward higher demand for bandwidth,mobile communication develops to higher frequency band such as millimeter wave,because the wide spectrum of W band(74-110 GHz)can meet the demand for high traffic,which provides a huge impetus for the research of W-band system.This paper presents and simulates a scheme of generating 90 GHz MMW generated by 30-tuple frequency optical MMW with high order sideband generated by using triangular wave signal as the RF signal driver dual drive Mach Incremental modulator(DDMZM)and using high nonlinear fiber(HNLF)to generate four-wave mixing effect(FWM)to further increase the frequency multiplier.Simulation results show that the experimental scheme can use 3 GHz RF signal to generate 90 GHz optogenic millimeter-wave signal,and carry 2.5 Gbit/s NRZ signal transmission 20 km,the eye map clear signal quality is good.In addition,the influence of HNLF length and the intensity of light signal into HNLF on FWM is analyzed,and the conditions for HNLF to generate the best±15 order sideband are obtained,so as to further optimize the whole system.
