本文主要对光控微波场效应管振荡器进行理论分析，并讨论了实验结果。有两种不同的控制方法：一种是对器件有源区的直接光控，另一种是引入光敏材料后的间接光控。除了可以对微波振荡器的频率进行光调谐之外，还可以利用光照控制振荡器的起振和停振，以及采用光注入锁定达到稳频 In this paper, the theoretical analysis of the light-controlled microwave FET oscillator and the experimental results are discussed. There are two different control methods: one is direct light control of the active area of ​​the device and the other is indirect light control after the introduction of the photoactive material. In addition to optical tuning of the frequency of the microwave oscillator, it is also possible to use light to control the start-up and stop-vibration of the oscillator as well as to achieve frequency stabilization using light injection locking
