which the notch is not located at the middle, and the value of is equal to about 0.42, as can be …

… reflective spectrum and the phase response of the filter. To demonstrate the effectiveness
of the method, the synthesis of a linear phase filter with small in-band dispersion is presented. …

… gratings has increased dramatically. This article reviews the technology of Bragg gratings in
