通过调节电光调制器的直流偏置来抑制一阶边带，然后利用双波导微环谐振器滤除光载波，产生了频率为10 GHz本振频率4倍的毫米波信号。提出了一种单片集成的硅基光学毫米波四倍频信号发生器。研制了一种硅集成微谐振滤波器，给出了设计参数。获得了高消光比的光毫米波信号。单边带噪声频谱的产生的40 GHz的光信号进行了测量，表现出类似的性能相比，由射频合成器产生的。
By adjusting the direct current (DC) bias on an electrooptic modulator to suppress the first-order sideband and subsequently using a double-waveguide micro-ring resonator to filter out the optical carrier, millimeter (mm)-wave signal was generated at a frequency of four times the 10-GHz local oscillator. A monolithic integrated silicon-based optical mm-wave signal generator by frequency quadrupling is proposed. A silicon integrated microresonator filter was fabricated and its design parameters are given. High extinction ratio optical mm-wave signal was obtained. The single sideband noise spectrum of the generated 40-GHz optical signal was measured, showing similar performance when compared with that generated by a radio-frequency synthesizer.
