Abstract :
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 methed.
