Unformatted text preview: Arrayed Waveguide Grating Router 5 Arrayed waveguide grating routers are used in fiber optic network telecommuni- cations as multiplexers, demultiplexers, add-drop filters, and as N N switches. The device, shown in the attached figure, consists of an array of channel waveguides with the optical path length of adjacent waveguides differing by a constant value. At the ends of the array of waveguides are input and output region slab waveguides. These slab wave- guide regions, in turn, are connected to input and output channel waveguides that are linked to individual optical fibers. The arrayed waveguide grating router can be conven- iently implemented as silica waveguides on a silicon wafer. The most basic operation of an arrayed waveguide grating router is perhaps as a demultiplexer. This type of operation may be characterized by considering multiple wavelengths in the input slab waveguide region incident at an angle i on the input to the arrayed waveguide grating region. The wavelengths are launched into all of the chan- nel waveguides of the arrayed waveguide region. The length of each channel waveguide is...
