Abstract
An apodised in-fibre Bragg grating reflector is fabricated using the p hase mask photoimprinting technique. The reflector has a centre wavele ngth of 1550nm, a bandwidth of 0.22nm and a peak of 90%. At 0.4nm (50G Hz) from the centre the reflectivity is 40dB lower than the peak refle ctivity; this is an improvement of more than 20dB over an unapodised B ragg grating reflector with similar bandwidth and peak reflectivity.
