摘要
对具有倾角的光纤光栅的反射特性进行了研究。得到了耦合系数随倾角变化的关系式。随着倾角的增大 ,耦合系数会减小 ,反射谱的中心波长会向长波长方向移动 ,而反射谱的形状不发生改变。
In this paper,we investigate the spectral and angular response of an optical fiber tilted-grating stucture in the frame of the coupled wave equation.Due to the period of fiber tilted-grating is larger than the period of non tilted fiber grating.It shifts the central wavelength of Reflectivity to a slightly longer wavelength.
