摘要：

In this paper, we analyze and propose a non-uniform transmission based ramp chirp grating which can give maximum negative dispersion profile over broadband wavelength range. Coupled mode theory is used for obtaining quantitative information about the delay spectral dependance of the grating structure. A matrix method is used for analyzing the grating characteristics. For a grating length of 25m, the grating can give negative dispersion of 266 ps/nm. When the grating is inserted after 16.07 kin in line with the existing fiber optic link, the maximum average compensated dispersion lies within +/-1.0 ps/nm-km over 1530 mn - 1560 am wavelength range.
