Abstract :
A chirped fibre Bragg grating, which was almost group delay ripple-free, has been achieved by inserting a beam containing a 100 mm-long, phase-error-free uniform grating and a metal rod into an S-shaped groove formed in a plastic substrate. The amplitude of the group delay ripple was less than ±3 ps around a centre wavelength of 1552.7 nm
