Design of Fiber Bragg Gratings for Mode-Locking Applications
Muhittin Sayin and M. Sadettin Ozyazici

In this paper, a model is presented for linearly chirped and Gaussian apodized gratings. The chirp term in the grating profile is included in a different form from those found in the literature. Using this model, the reflection spectrum and group delay characteristics of the gratings are examined. The effects of the index modulation, wavelength chirp and the grating length on these characteristics are determined. It is found that the grating must be linearly chirped, and its length and refractive index modulation must be optimized in order for the grating to be used in special applications requiring wide mode-locking frequency range.
