Recently, with the increasing traffic in data centers (DCs) and the evolution of high-performance computers (HPCs), large-capacity data transmission has been required in DC and HPC networks. To take advantage of optical interconnects with the capability of transmitting high-speed signals under high wiring density, we have proposed active optical modules for inter-rack interconnects in DC and HPC networks. In order to satisfy the higher bandwidth demand, not only the inter-rack interconnects but also on-board interconnects are required to have a high density. In this paper, we propose a high-density optical module utilizing graded-index (GI) polymer waveguide for on-board optical interconnects.
