4.7 Comparisons between reflectivity and bandwidth for different cascaded units of apodized fiber Bragg grating

Table 1 show different cascaded apodized fiber Bragg grating variations of reflectivity, R and bandwidth with the increase of number of stages.

From Table 1 we noted that as the number of cascaded units of fiber Bragg grating is increased the reflectivity is slightly decreased and the bandwidth decreased with minimum side lobes.
