Chirped in-fibre Bragg grating dispersion compensators: linearisation of dispersion characteristic and demonstration of dispersion compensation in 100 km, 10 Gbit/s optical fibre link

An apodised chirped in-fibre Bragg grating that has a linear dispersion characteristic is reported. The frequency components of an optical pulse (centre wavelength 1551 nm: 10 GHz bandwidth) incident on the grating are reflected with a relative delay that varies linearly from 0 to 130 ps across the spectral width of the pulse. The dispersion compensator is used to correct for the dispersion in a 100 km link (nondispersion shifted fibre) operating at a 10 Gbit/s transmission rate and a wavelength of 1551 nm.< >
