GlobalFoundries and Ayar Labs, a startup bringing optical input/output (I/O) to silicon chips, announce a strategic collaboration to co-develop and commercialize differentiated silicon photonic technology solutions. The companies will develop and manufacture Ayar’s novel CMOS optical I/O technology, using GF’s 45nm CMOS fabrication process, to deliver an alternative to copper I/O that offers up to ten times higher bandwidth and up to five times lower power. This cost-effective solution is integrated in-package with customer ASICs as a multi-chip module, and improves data speed and energy efficiency in cloud servers, datacenters and supercomputers. As part of the agreement, GF has also invested an undisclosed amount in Ayar Labs.
Modern data centers and cloud applications require high-performance, power-hungry chips to process and analyze huge volumes of data in real time. Growth in chip I/O capabilities has not matched exponential increases in computing power, because of physical limitations in electrical data transmission. Optical I/O, which leverages optical components on the CMOS die to transmit data at rapid speeds, will be a key enabler to overcoming the limitations of today’s data center interconnects. In addition, Ayar’s technology reduces power consumption at both the network and processor level.
The collaboration brings together Ayar Labs’ patented IP in optical technology with GF’s best-in-class expertise in silicon photonics to co-develop optical solutions that will be fabricated using GF’s process technology. The availability of this technology, including certain Design IP cores, will enable internet service providers, system vendors and communication systems to push data capacity to 10 Tera bits per second (Tbps) and beyond, while maintaining the low energy and cost of optical-based interconnects.
