Abstract
We propose a new type of fiber Bragg grating (FBG) with a V-shaped dispersion profile. We demonstrate that
such V-shaped FBGs bring advantages in manipulation of optical signals compared to conventional FBGs with a constant
dispersion, e.g., they can produce larger chirp for the same input pulsewidth and/or can be used as pulse shapers.
Application of the proposed V-shaped FBGs for signal prechirping in fiber transmission is examined. The proposed
design of the V-shaped FBG can be easily extended to embrace multichannel devices.
