GloFo puts optical I/O on 45nm CMOS


NPLs ion microchip

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 10x higher bandwidth and up to 5x lower power. T

his 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.

“This collaboration between Ayar and GF could improve chip communication bandwidth by more than an order of magnitude and at lower power, and is a validation of Ayar’s viability in the current semiconductor ecosystem.,” says Ayar Labs’ Alex Wright-Gladstein, “this collaboration will unlock a larger market opportunity, expanding both our and GF’s customer base. We look forward to working with GF to help solve the interconnect problems of today’s chips and create greater value for our customers than if both companies worked independently.”

“The Ayar Labs team has been designing cutting-edge silicon photonics components on GF’s technology for the past eight years and has achieved exceptional results,” says GloFo’s  Mike Cadigan,  “our strategic collaboration builds on our relationship, leveraging GF’s silicon photonics IP portfolio and our world-class manufacturing expertise to enable faster and more energy-efficient computing systems for data centers.”

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.
