The coupler-mode equation for analysing Bragg-grating reflection coupler was presented. The influences of different gratings’ position in the coupling region and grating length on the filtering spectra were investigated based on the equation. A Bragg-grating reflection coupler with reflectivity 20dB was achieved by fused taper technology and Phase Mask method.
