Abstract
Wavelength multi/demultiplexers with 1 nm spacing have been realised w ith an asymmetric 2 x 2 Mach-Zehnder interferometer in silica-on-silic on. Heating one arm of the interferometer allows for wavelength tuning or wavelength switching of the outputs. Switching or tuning over 1 nm is achieved with only 95mW within rise and fall times added to of 150 and 220 mu s, respectively. Tuning and switching can be separated, as temperature changes in the substrate also result in wavelength shifts .
