An optical waveguide interconnect mesh network scheme for parallel multiprocessor systems based on an electro-optical printed circuit board(EOPCB) with multimode polymer waveguide is proposed.The system consists of 2×2 processor element chips interconnected in a mesh network configuration.An additional layer with optical waveguide structure is embedded in a conventional printed circuit board to construct the EOPCB.Vertical cavity surface emitting laser(VCSEL)/positive intrinsic-negative(PIN) arrays are applied as the optical transmitters/receivers.Three 1×12 VCSEL/PIN parallel optical transmitting/receiving modules are used to provide 32 input/output optical channels required by the 2×2 chip-to-chip optical mesh interconnect system.The data rate in each optical channel is 3.125 Gbps and thus 10 Gbps parallel optical interconnect link for each direction of a chip is obtained.The optical signals from a processor element chip can be transmitted to another chip through optical waveguide interconnect embedded in the board.Thus the optical interconnect mesh network for parallel multiprocessor system can be implemented.
