Abstract
An arrayed waveguide grating (AWG) based multi-core and multi-wavelength interconnection network, comprising N upper-level switches, N lower-level switches, and a network intermediate stage, with each upper- and lower-level switches has N CWDM optical transceiving modules. The N optical transceiving modules of each upper-level switch is connected with n m×1 multi-core optical multiplexing modules, the N optical transceiving modules of each lower-level switch is connected with n 1×m multi-core demultiplexing modules, the network intermediate stage is comprised of n2 r×r multi-core and multi-wavelength wiring modules. The upper-level multi-core optical multiplexing modules, the lower-level multi-core demultiplexing modules, and the n2 r×r multi-core and multi-wavelength wiring modules of the network intermediate stage are connected via an m-core MPO-MPO optical fiber jumper. The wiring complexity of the interconnection network is O(N2/r), with employment of a wavelength set of Λ={λ0, . . . , λk-1}. The present invention conserves wavelength resources of communication windows, enhances scalability of the AWG based interconnection network, while reduces network wiring complexity.
