Expression of Reflection-Peak Wavelengths of Arbitrary Chirped and Sampled Fiber Bragg Gratings
We present an analytical expression for sampled fiber Bragg gratings (SFBGs) with arbitrary chirps in sampling function or grating period or combination of both. The relationship among the wavelength of each channel, the chirp coefficient of the sampling and the grating period, and the total length of the grating is explicitly given. Specifically, the chirped sampling function is first expanded into a new function using Fourier theory; the equivalent local Bragg period is then obtained to derive the expression of the reflection peak wavelength. The overall wavelength position is obtained by summation of both contributions from sampling chirp and the grating chirp. The calculated results based on the analytical expression are examined with the conventional numerical results, which are found to be in excellent agreement.
