摘　　要：A novel 2×2 wavelength selective cross-connect (WSXC) module, which is composed of a Bragg-grating-based Mach- Zehnder interferometer (MZI), a pair of optical waveguides, a pair of 1×2 optical switches (OSWs) and a pair of Y-model combiners is proposed. The mathematical description of the proposed 2×2 WSXC module is given and explained. Multi- channel multi-wavelength selective cross-connect can be fabricated with the proposed 2×2 WSXC module, together with multistage interconnection networks (MINs). A four-wavelength 4×4 WSXC is demonstrated by simulation to validate the flexibility of the proposed WSXC.A novel 2×2 wavelength selective cross-connect （WSXC） module, which is composed of a Bragg-grating-based Mach-Zehnder interferometer （MZI）, a pair of optical waveguides, a pair of 1×2 optical switches （OSWs） and a pair of Y-model combiners is proposed.
