A NOVEL INTEGRATED-OPTIC WDM CROSS-CONNECT FOR WIDE AREA ALL-OPTICAL NETWORKS

In this paper, we propose a novel design for an integrated-optic WDM c ross-connect which can be used in various wavelength routing network a pplications. This device is based on integrating a two-dimensional arr ay of Bragg diffraction cells at cross points of input/output co-plann er waveguides. The wavelength tuning of the individual Bragg cells can be chosen to construct a WDM cross-connect, with any number of requir ed input/output interconnections. These cross-connects have proven ext remely important in the design and deployment of wide area/nationwide all-optical networks.
