Abstract

The influence of the position and the length of the Bragg grating written into conventional 2×2 fused couplers on its spectral response is numerically investigated and analyzed. It is possible to realize optical add and drop multiplexers with conventional fused couplers as well as with photosensitive couplers, and there is an optimized position and appropriate length of grating to obtain high reflectivity from drop port. In order to improve the characteristics of the component, a nonlinear chirped grating is proposed to be written into the coupler. According to the parameters in simulation, component with larger than 10dB reflectivity and bandwidth >1nm is obtained by inscribing a uniform Bragg grating in fusion region of the 3dB coupler experimentally.
