提出了一种利用光纤法布里-珀罗（FFP）可调谐滤波器同时实现相位-强度调制转换（PM-IM）和效率提高的新方法。为了实现相位调制到强度调制的转换，相位调制光从FFP可调谐滤波器的斜坡之一透射，以打破边带的幅度平衡。同时，由于光载波比一阶边带中的一个受到更多的抑制，调制深度增加。结果表明，PM-IM转换已经实现，并且对于10-和20-GHz微波输入，适当的光载波抑制可以获得约10-dB的电信号功率增益。© 2010 Wiley Periodicals，Inc.

A novel method is proposed and demonstrated to simultaneously realize phase‐to‐intensity modulation conversion (PM‐IM) and efficiency improvement using a fiber Fabry‐Perot (FFP) tunable filter. To achieve the conversion of phase modulation to intensity modulation, the phase‐modulated light is transmitted from one of the slopes of the FFP tunable filter to break the amplitude balance of the sidebands. Meanwhile, the modulation depth is increased due to the more suppression of the optical carrier than one of the first‐order sidebands. The results demonstrate that the PM‐IM conversion has been achieved and an about 10‐dB gain of electrical signal power could be obtained with suitable optical carrier suppression for both 10‐and 20‐GHz microwave input. © 2010 Wiley Periodicals, Inc.
