实验证明了一种在半导体光放大器（SOA）中基于四波混频（FWM）产生三倍频率毫米波信号的方法。在该系统中，利用光锁相环（OPLL）产生的两个相位相关光波长作为两个泵浦来产生SOA中的FWM过程。得到两个波长间隔为两个泵浦波长三倍的空转器。两个泵浦波长然后被两个级联光纤布拉格光栅作为光学陷波滤波器去除。通过在光电探测器上敲打两个惰轮，产生频率为OPLL参考源三倍的毫米波
An approach to generating a frequency-tripled millimeter-wave (mm-wave) signal based on four-wave mixing (FWM) in a semiconductor optical amplifier (SOA) is experimentally demonstrated. In the proposed system, two phase-correlated optical wavelengths generated by an optical phase-locked loop (OPLL) are used as two pumps to generate the FWM process in the SOA. Two idlers with a wavelength spacing three times that of the two pump wavelengths are obtained. The two pump wavelengths are then removed by two cascaded fiber Bragg gratings serving as an optical notch filter. By beating the two idlers at a photodetector, an mm-wave with a frequency that is three times that of the OPLL reference source is generated
