【摘要】：由于有效利用了光子技术的优点,微波光子技术克服了传统微波系统中的一些瓶颈,从而提高已有系统性能,甚至开发出了全新的系统应用。很多光子器件已经被用在微波光子系统中,光纤布拉格光栅(Fiber Bragg grating,FBG)就是其中一种非常重要的全光纤器件。由于具有灵活的频谱响应特性、损耗低、质量轻、结构紧凑、以及与其他光纤器件耦合性好等独特的优势,光纤布拉格光栅已经成为了微波光子信号处理系统中的关键组件之一。本文主要介绍了近年来光纤布拉格光栅在微波光子信号处理应用中的最新进展,重点讨论的主要应用包括微波光子滤波器,微波任意波形产生,微波频谱感知以及光纤光栅传感器实时解调。最后,本文还讨论了在微波光子系统中应用光纤布拉格光栅的局限性及可能的解决方案。
[Abstract]:Because of utilizing the advantages of photonic technology effectively, microwave photonic technology overcomes some bottlenecks in traditional microwave systems, thus improving the performance of existing systems, and even developing a new system application. Many photonic devices have been used in microwave photonic systems, fiber Bragg grating fiber Bragg gratings (FBGs) is one of the most important all-fiber devices. Because of its flexible spectrum response characteristics, low loss, light weight, compact structure and good coupling with other optical fiber devices, Fiber Bragg grating has become one of the key components in microwave photon signal processing system. In this paper, the latest progress of fiber Bragg grating in microwave photonic signal processing is introduced. The applications of fiber Bragg grating in microwave photonic signal processing are mainly discussed, including microwave photonic filter, microwave arbitrary waveform generation. Microwave spectrum sensing and real-time demodulation of fiber grating sensor. Finally, the limitations and possible solutions of fiber Bragg gratings in microwave photonic systems are discussed.
