描述了一种调整光纤光栅色散分布的新方法。该方法涉及压缩附接至横截面积随其位置而变化的结构的光纤光栅。由于横截面积定义了压缩率，因此决定色散分布的局部布拉格反射波长沿位置变化。设计了一种可以通过插入和拔出结构的一部分来简单地改变横截面积的结构。因此，可以选择附着在结构上的光纤光栅的色散阶数。使用该方法，制作了线性二次啁啾光纤光栅，并获得了取决于所施加应力的各种群延迟斜率。
A new method for tuning the dispersion profile of a fiber grating is described. The method involves compressing the fiber grating attached to a structure in which the cross-sectional area varies with its position. Because the cross-sectional area defines the compression rate, the local Bragg reflection wavelength that determines the dispersion profile varies along the position. A structure in which the cross-sectional area can be simply altered by inserting-extracting a part of structure was designed. Therefore, the dispersion order of the fiber grating attached to the structure can be selected. Using the method, a linearly-quadratically chirped fiber grating was made and various group delay slopes depending on the applied stress were obtained.
