GUIDED-WAVE OPTICAL EQUALIZER WITH ALPHA-POWER CHIRPED GRATING

This paper presents a theoretical investigation of a guided-wave optic al equalizer with an alpha-power chirped grating. A group delay disper sion of 3700 ps/nm can be obtained at lambda = 1.55 mum by the chirped grating with alpha = 0.3. It is shown that the chromatic dispersion o f 200 km of a fiber whose zero dispersion wavelength is located at 1.3 mum can be compensated at 1.55 mum to achieve up to 10 GHz signal ban dwidth.
