光子晶体光纤光栅是一种新型的无源器件，可广泛用于光纤通信系统、光脉冲压缩、传感器及滤波装置中。采用耦合模理论对光脉冲在光子晶体光纤光栅中传播进行分析，给出光子晶体光纤光栅的制作方案，提出了光子晶体光纤光栅在压力传感器、折射率传感器、应变传感器和射流传感器等方面的具体应用。光子晶体光纤光栅对温度的敏感性比传统单模光纤传感器要低2至3个数量级，光子晶体光纤光栅传感器系统不需要温度补偿，传感器系统更为简洁而具备充分的优越性。

As a new passive device, photonic crystal fiber grating can be widely used in optical fiber communication systems, optical pulse compression, sensors and filtering devices. With the coupled-mode theory, this paper analyzes the optical pulses propagation in photonic crystal fiber gratings, and the obtained methods of photonic crystal fiber gratings. It summarizes its applications in photonic crystal fiber grating pressure sensor, the refractive index sensors, strain sensors and the fluidic sensors. The temperature sensitivity of photonic crystal fiber grating is at lower 2-3 orders of magnitude than that of conventional single-mode fiber, photonic crystal fiber grating sensor does not need temperature compensation, so this sensors is more concise and sufficiently superior.
