摘　　要：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 ap- plied 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.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.
