OFC 2023: Sivers Photonics, Ayar Labs demo CW-WDM MSA compliant DFB laser arrays

Sivers Photonics has successfully demonstrated its continuous-wave wavelength division multiplexing multi-source agreement (CW-WDM MSA) compliant distributed feedback (DFB) laser arrays with Ayar Labs’ SuperNova remote optical source, supporting next generation applications including AI connections, disaggregated data centres, 6G, phased array sensory systems and more.

The live demonstration taking place at the Sivers Photonics booth (#5400) throughout OFC shows two SuperNova modules, each with 64 total wavelengths, running without active cooling.

Built on the InP100 product platform at Sivers 100mm UK wafer foundry, the DFB laser array is fully compliant with CW-WDM MSA standards, with an output power of more than 65mW per channel CW operation and 400 GHz channel spacing around 1300 nm. These devices are compatible in a variety of integration platforms, such as silicon photonics and co-packaged optics (CPO).

The SuperNova optical source provides up to 16 wavelengths of light, powering up to 16 ports. Combined with Ayar Labs’ TeraPHY optical I/O chiplet, this complete solution delivers up to 4 terabit per second bi directional data throughput, with nanosecond (ns) latency, whilst consuming a fraction of the power required for traditional electrical I/O.

Anders Storm, Group CEO, Sivers Semiconductors says: “It is a great pleasure to work with Ayar Labs as they continue to showcase technology leadership with Sivers Photonics support with this live silicon photonics demonstration. Our DFB arrays contribute to Ayar Labs industry-first milestone using the Global Foundries SiPi platform which will help unleash the power of next generation computing.”

William McLaughlin, managing director at Sivers Photonics adds: “As communication traffic grows rapidly, we are pleased to enable Ayar Labs to deliver the optical interconnects needed for these data-intensive applications. We are thrilled to demonstrate our joint technology live, at one of the industry’s top events.”

Matt Sysak, Vice President of Laser Engineering at Ayar Labs says: “We are thrilled to continue our partnership with Sivers Photonics. Their InP100 laser arrays are a vital part of the technology helping to drive adoption of in-package Optical I/O.”
