摘　　要：详细阐述了国内外几种典型光子晶体光纤光栅的制备方法,如紫外曝光法、热激成栅法、机械压力法、双光子吸收法,并分析了各自的优缺点,还分析了光于晶体光纤布拉格光栅、长周期光栅的模式耦合特性。研究表明:光子晶体光纤光栅具有对外界折射率不敏感的特性,且在纯硅纤芯写制的光栅还具有对温度不敏感的特性。简要介绍了光子晶体光纤光栅在光通信及光传感领域中的应用,并对基于光子晶体光纤光栅的薪型光于器件进行了展望。Typical fabrication methods of photonics crystal fiber gratings are studied, such as by ultraviolet beams, CO2 laser heat source, mechanical pressure, two-photon absorption at home and abroad. The mode coupling properties of fiber Bragg gratings and long period gratings written in photonics crystal fibers are analyzed. Photonic crystal fiber gratings are insensitive to external conditions and gratings written in pure silicon core are also insensitive to temperature. Finally, the applications of photonic crystal fiber gratings in optical fiber communication and sensing system and the prospect of photonic crystal fiber grating based devices are presented
