光频发生器可以发生比现用设备更低噪声和更低功耗的射频输出。由加州理工学院喷气推进实验室R．Logan申请专利的光学射频合成器产生具有1～100GHz以上频率范围的相位稳定、强度调制的光载波。利用光纤的多数应用，包括从通信到射频天文学都可从强度可调的微波和毫米波频率信号 Optical frequency generator can occur than existing equipment, lower noise and lower power RF output. Jet Propulsion Laboratory by California Institute of Technology. Logan’s patented optical RF synthesizer produces phase-stabilized, intensity-modulated optical carriers with frequencies in the 1-to-100-GHz range. Most applications that make use of optical fiber, from communications to radio astronomy, are available from intensity-adjustable microwave and millimeter-wave frequency signals
