【 摘 要 】

References(9)Cited-By(1)We demonstrate a Colorless, Directionless, and Contentionless add/drop that is made possible by newly proposed multi-stage tunable filters; it will be effective in the creation of flexible and dynamic optical path networks. The filters consist of small-scale switches and AWGs (Arrayed Waveguide Gratings) and so are cost effective. The technical feasibility of the drop configuration using proposed tunable filters is experimentally verified.
