Fiber Bragg grating too large
They can be largely removed with the technique of apodization: the strength of the index modulation is smoothly ramped up and down along the grating. Of course, one then needs an increased overall length of the grating to achieve a certain peak reflectance. A fiber Bragg grating is a periodic or aperiodic perturbation of the effective refractive index in the core of an optical fiber (see Figure 1). a few millimeters or centimeters, and the period is of the order of.
