摘要

针对高倍频毫米波的产生问题，文章提出了一种基于4个偏振调制器并联产生16倍频毫米波的方案，利用相关光边带极性的不同，使合成光信号中只保留载波和8

阶边带。经过适当选取调制指数值和光电探测器拍频后，获得16倍频毫米波信号。文章理论分析了产生16倍频毫米波信号的原理，推导出方案所产生的±8阶光边带信号的光边带抑制比为61.72 dB，16倍频毫米波信号的射频杂散抑制比为55.70 dB。仿真实验获得的光边带抑制比和射频杂散抑制比分别为60和53 dB。同时分析了射频信号相位偏移及调制指数对抑制比的影响。实验结果与理论分析吻合，验证了所提方案的可行性。

Abstract

In order to generate high-frequency millimeter-wave

this paper proposes a scheme of generating 16-tupling millimeter wave signal with 4 polarization modulators in parallel

using the different polarities of optical sideband to merely reserve optical carrier and the 8

th-order sidebands. By properly selecting the modulation index

we can get the±8th-order optical sideband signal with carrier suppressed. Finally

after the composite optical signals beaten on the photodetector

the 16-tupling millimeter-wave signal is achieved. The principle of generating 16-tupling millimeter-wave signal is theoretically analyzed. The optical sideband suppression ratio of the obtained±8th-order sideband signal is 61.72 dB

and the radio frequency stray suppression ratio of the 16-tupling millimeter-wave signal is 55.70 dB. The optical sideband suppression ratio and the radio frequency stray suppression ratio obtained from the simulation are 60 dB and 53 dB

respectively. The effects of phase offset and modulation index on sidebands suppression ratio are also analyzed. The experimental results are consistent with the theoretical analysis

which can verify the feasibility of the proposed scheme.
