Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. The book describes the AWG design procedure by applying a new software tool. An INTERCONNECT compact model is initially used for quick analysis.
The problem of coupling electromagnetic or acoustic waves into a dielectric waveguide with minimal energy loss is formulated as a structural (topology) op-timization problem. Optimal solutions are shown.
