As the signal speed of LSIs increases, so does the need to replace copper interconnects with optical interconnects, especially for high performance computing (HPC). The LSIs of next-generation HPC have as many as approximately 1,000I/O signals, so the optoelectronic module for them has to be small. We developed high-density optoelectronic modules that have 12 channels operating at 10Gbps with a 4.5×4.5-mm substrate that has small electrode pads for mounting optical devices on the side face. We demonstrated 10-Gbps transmission between two prototype LSIs using the optoelectronic modules. 10-Gbps signal was transmitted from an LSI to another LSI through electrical-optical-electrical signal path, and error free operation (BER<1E-12) was achieved.
