Demand for higher data throughput and higher interconnect densities in servers and routers for IT network systems is growing quickly. Optical interconnects have both speed and high-density. There are more developments in optical interconnection, and we outline those from Japan with an opt-electronics package point of view.
A low-voltage, 90-nm CMOS optical interconnect transceiver operating at 1550-nm optical wavelength is presented. This is the first demonstration of a novel optoelectronic modulator architecture (the quasi-waveguide angled-facet electroabsorption modulator) in a system. It features a simple electronic packaging via flip-chip bonding to silicon. Devices have a broad optical bandwidth, are arrayed two...
To implement an optically-data-linked computer system, we proposed a chip-to-chip optical interconnection platforms based on fiber-embedded printed-circuit boards (PCBs) and fiber-optic components for assembly. The 90deg deflection of light between the optical PCB and transceiver modules were achieved using 90deg-bent fiber blocks. The connection blocks and optical transceiver modules were passively...
