Abstract :
The authors report the realisation of a new UV written fibre bandpass filter composed of two quarter-wave shifts inserted in a short Bragg grating. This new resonator presents a wider transmission band than classical singly phase-shifted grating of equal lengths and equivalent rejection bandwidths
