High-Density Power-Efficient Parallel Multi-Wavelength Optical Interconnect for Computer Systems

This paper describes a 3 W 500-Gbps (4x12x10.42-Gb/s) parallel wavelength-division multiplexed optical interconnect that uses a 12-fiber ribbon with 4 wavelengths per fiber. The transmitter and receiver are each 5mm x 8 mm chip-scale packages.
