TERABOARD aims at demonstrating a scalable, low power, low cost photonic technology to sustain the continuous increase of bandwidth density by leveraging on combination of scalability and low energy consumption. TERABOARD is a new technology that enables very large aggregated bandwidth density (Tb/s/cm2) on board. The concentration of a large number of operations in a single board leads to a radical system innovation, reduction of total energy cost and reduction of hardware size and cost.
