Abstract :
The authors report the performance of an optical add-drop multiplexer made in silica-on-silicon waveguides by writing Bragg gratings in a Mach-Zehnder interferometer. The isolation between the add and the drop channels is better than 50 dB and the crosstalk between two adjacent channels is <-27 dB
