Summary
| DescriptionArrayed-Waveguide-Grating.svg |
English: An Arrayed-Waveguide Grating is an optical de-/multiplexer used in telecommunication. The incoming light (1) traverses a free space (2) and enters a bundle of optical fibers or channel waveguides (3). The fibers have different length and thus apply a different phase shift. At the exit of the fibers (3) the light traverses another free space (4) and interferes at the entries of the output waveguides (5) in such a way that each output chanel receives only light of a certain wavelength. The orange lines only illustrate the light path. The light path from (1) to (5) is a demultiplexer, from (5) to (1) a multiplexer.
Deutsch: Ein Arrayed-Waveguide Grating ist ein optischer De-/Multiplexer aus der Telekommunikation. Er kann Licht verschiedener Wellenlängen, das durch einen Lichtwellenleiter (1) ankommt, verlustarm auf verschiedene Ausgangslichtwellenleiter (5) verteilen. Das Licht durchläuft einen Freistrahlbereich (2) und wird in eine Anordnung von Lichtwellenleitern unterschiedlicher Länge (3) eingespeist. Nach dem Austritt aus diesen Wellenleitern interferrieren die einzelnen Teilstrahlen in einem weiteren Freistrahlbereich (4) so, dass in jeden Ausgangswellenleiter (5) jeweils nur das Licht einer bestimmten Wellenlänge eintreten kann. Die orangefarbenen Linien dienen nur der Illustration des Lichtweges. Der Lichtweg von (1) nach (5) funktioniert als Demultiplexer, von (5) nach (1) als Multiplexer. |
