有三个联合的洞的一个新单个模式的 optoelectronic 振荡器(OEO ) 被建议并且示威。在 F-P 洞纤维激光担任轻来源的地方, Fabry-Perot ( F-P )洞纤维激光和一个光电的反馈分支一起被联合构造一个 optoelectronic 振荡器,并且一个调节的人被放在激光洞实现互给调整,它同时把激光洞切成二部分并且形成一种双环的配置。完成一个 optoelectronic 振荡器,光信号的部分是来自 F-P 洞的输出实现反馈调整,它构造第三个洞。因为仅仅摆动信号满足所有三个洞的要求,单个模式的摆动能最后被完成。没有增加更多的 optoelectronic 设备,三个反响的洞成功地被设计,并且方面模式能是与低费用压制的井。摆动条件理论上被分析。在试验性的示范, 20 GHz 单个纵的模式微波信号成功地被获得。
A new single-mode optoelectronic oscillator(OEO) with three coupled cavities is proposed and demonstrated. A Fabry-Perot(F-P) cavity fiber laser and an optical-electrical feedback branch are coupled together to construct an optoelectronic oscillator, where the F-P cavity fiber laser serves as a light source, and a modulator is placed in the laser cavity to implement reciprocating modulation, which simultaneously splits the laser cavity into two parts and forms a dual-loop configuration. To complete an optoelectronic oscillator, part of optical signal is output from the F-P cavity to implement the feedback modulation, which constructs the third cavity. Since only the oscillation signal satisfies the requirements of all the three cavities, a single-mode oscillation can be finally achieved. Three resonant cavities are successfully designed without adding more optoelectronic devices, and the side-modes can be well suppressed with low cost. The oscillation condition is theoretically analyzed. In the experimental demonstration, a 20 GHz single longitudinal mode microwave signal is successfully obtained.
