Phased array WDM

It is very likely that integrated components will obtain a breakthrough in connection with WDM (Wavelength Division Multiplex) systems, and by participating in METON we have designed a number of components, the most complicated being the Phased Array unit. Splitting the signal from one waveguide into a large number of waveguides and combining these again, it is possible to create a filter with a number of pass/stop bands. We have used two different numerical methods for analyzing this component, and obtained a very good agreement with results measured on devices manufactured at MIC. Especially the Far Field Pertubation Method is very suitable for optimization of such a component.
