Abstract :
An apodised in-fibre Bragg grating reflector is fabricated using the phase mask photoimprinting technique. The reflector has a centre wavelength of 1550 nm, a bandwidth of 0.22 nm and a peak reflectivity of 90%. At 0.4 nm (50 GHz) from centre wavelength the reflectivity is 40 dB lower than peak reflectivity; this is an improvement of more than 20 dB over an unapodised Bragg grating reflector with similar bandwidth and peak reflectivity
