摘　　要：基于阵列波导光栅的光子集成解调技术是硅光领域的研究热点和难点.相比传统解调方法,基于阵列波导光栅的光子集成解调技术因其解调精度高、解调速度快、封装体积小等优势,在光纤布拉格光栅的高速、高精度解调上具有明显优势.近年来,随着光子集成技术的发展,各科研院所和相关机构对阵列波导光栅的光子集成解调法进行了广泛深入的研究与优化.本文通过介绍阵列波导光栅工作原理及基于阵列波导光栅的光纤布拉格光栅波长解调原理,结合基于阵列波导光栅的光纤布拉格光栅解调仪在材料体系和系统性能两个方面的重要进展,归纳了基于阵列波导光栅的解调仪的典型应用场景,从新材料、系统集成和规模化三方面对光纤布拉格光栅解调系统的未来发展提出针对性建议,为基于阵列波导光栅的光子集成解调技术的研究发展提供参考.The photonic integrated interrogation technology based on array waveguide grating is a hot but difficult research area in the silicon optical field.Compared with traditional interrogation methods,the photonic integration interrogation technology based on an array waveguide grating has obvious advantages in high-speed and high-precision demodulation of fiber Bragg gratings due to its high demodulation accuracy,fast demodulation speed,and small package size.In recent years,with the development of photonic integration technology,various research institutions and relevant organizations have conducted extensive and in-depth research and optimization on the photonic integration interrogation method of array waveguide gratings.In this paper we introduce the working principle of array waveguide grating and the principle of fiber Bragg grating wavelength interrogation based on array waveguide grating,the important progress of fiber Bragg grating interrogator based on array waveguide grating in both material system and system performance,and summarize the typical applications in interrogator based on array waveguide grating.The future development of fiber Bragg grating demodulation system is proposed from three aspects:new materials,system integration,and scale-up,which provides a reference for the research and development of photonic integrated interrogation technology based on array waveguide grating.
