Title (EN) OPTICAL CHANNEL-TO-WAVELENGTH TUNING
(FR) SYNTONISATION DE CANAL OPTIQUE EN LONGUEUR D'ONDE
Abstract:
(EN) An optical system includes an optical transmitter having optical transmission channels and an optical receiver having optical reception channels. The optical transmission channels are successively tuned to resonant wavelengths at which lowest transmission channel input currents result in transmission channel output current peaks greater than a threshold. The optical reception channels are tuned to the resonant wavelengths after the optical transmission channels are tuned. Each resonant wavelength has the optical reception channel tuned thereto that has a highest reception channel output current peak at a lowest reception channel input current when the optical transmission channel tuned to the resonant wavelength is temporarily detuned.
(FR) L’invention concerne un système optique comprenant un émetteur optique ayant des canaux de transmission optique et un récepteur optique ayant des canaux de réception optique. Les canaux de transmission optique sont successivement accordés à des longueurs d'onde de résonance auxquelles les courants d'entrée de canal de transmission les plus bas conduisent à des pics de courant de sortie de canal de transmission supérieurs à un seuil. Les canaux de réception optique sont accordés sur les longueurs d'onde de résonance après que les canaux de transmission optique sont accordés. Chaque longueur d'onde de résonance possède le canal de réception optique syntonisé à celle-ci qui a un pic de courant de sortie de canal de réception le plus élevé à un courant d'entrée de canal de réception le plus bas lorsque le canal de transmission optique syntonisé à la longueur d'onde de résonance est temporairement désyntonisé.
