从光栅周期、折射率调制深度、包层半径和芯层半径对长周期光纤光栅的谐振波长的影响进行了研究。这些结果对于选择合适的光纤合理设计光栅周期以增加其敏感性具有一定的意义。
The effects of grating period, refractive index modulation depth, clad radius and core radius on the resonant wavelength of long-period fiber gratings have been studied. These results have some significance for choosing the appropriate optical fiber to rationally design the grating period to increase its sensitivity.
