  • Abstract
    A novel method for tuning the centre wavelength of silica waveguide type Mach-Zehnder multi/demultiplexers (MUX/DEMUXs) has been devised. This tuning is achieved by irradiating a CO2 laser beam onto either arm of the Mach-Zehnder interferometer. In a MUX/DEMUX for channel spacing of 20 nm, the centre wavelength is tuned about 3 nm and the results closely agree with the calculation.
