"Terabus" - A waveguide-based parallel optical interconnect for Tb/s-class on-board data transfers in computer systems

Technologies for Tb/s-class optical links are demonstrated, including an organic card with 48 integrated waveguides and a silicon-carrier interposer. 4x12-array optical transmitters and receivers operate up to 20Gb/s and 14Gb/s per channel, respectively, with <10mW-per-Gb/s link power dissipation.
