Abstract :
Asymmetrically apodised linearly-chirped fibre Bragg gratings (FBGs) are shown to have highly linearised time-delay response. In simulations of a five-stage, 5-cm grating-based dispersion compensation system, asymmetrically apodised FBGs are shown to give over 60% reduction in the energy scattered from the main pulse body, for 16 ps to 60 ps pulses propagated over 800 km, as compared to a symmetrically apodised grating
