Guided-wave optical equalizer with alpha -power chirped grating

A theoretical investigation of a guided-wave optical equalizer with an alpha -power chirped grating is presented. A group delay dispersion of 3700 ps/nm can be obtained at lambda =1.55 mu m by a chirped grating with alpha =0.3. It is shown that the chromatic dispersion of 200 km of a fiber whose zero-dispersion wavelength is located at 1.3 mu m can be compensated at 1.55 mu m to achieve up to 10 GHz signal bandwidth.>
