DISPOSITIF DE TRAITEMENT OPTIQUE A MULTIPLEXAGE PAR REPARTITION EN LONGUEURS D'ONDE ET VOIE DE TRANSMISSION DE COMMUNICATION OPTIQUE

摘要

A wavelength division multiplexed optical processing device and an optical communication transmission path which are capable of significantly improving the transmission characteristic of wavelength division multiplexed optical signals. A wavelength division multiplexed optical processing device is formed by a first arrayed optical waveguide for demultiplexing entered wavelength division multiplexed optical signals, and outputting demultiplexed optical signals; a plurality of correction units for correcting respective optical signals demultiplexed by the first arrayed optical waveguide; and a second arrayed optical waveguide for multiplexing optical signals corrected by the correction unit, and outputting multiplexed optical signals. An optical communication transmission path is formed by an optical transmission path; and at least one wavelength division multiplexed optical processing device using an arrayed optical waveguide having a transmission wavelength characteristic with a flat top shape, which is inserted into the optical transmission path at a prescribed interval.
