The SCINTIL Comb Laser Source allows for uncooled Dense Wavelength Division Multiplexing (DWDM) links with twice the density of optical carriers.

SCINTIL Comb Laser Source by Scintil Photonics is a single-chip multi-port 100 GHz DFB Comb Laser Source that significantly enhances computing system performance and power efficiency in high-performance computing and AI applications. It is the first fully integrated single chip that achieves 100-GHz frequency spacing, offering twice the number of optical carriers compared to existing solutions and enabling doubled transmission speed. The SCINTIL Comb Laser Source allows for uncooled Dense Wavelength Division Multiplexing (DWDM) links with twice the density of optical carriers. Moreover, it supports configurations for transmitting 16 optical carriers at 64 Gbps per fibre, making it ideal for next-gen optical compute interconnect links. The solution offers very narrow controlled channel spacing, that can enable increasing the number of optical carriers in a single fibre. Scintil’s technology has the potential to be a game-changer in interconnects for high-performance computing and AI applications.

“We are thrilled to showcase our latest innovation, a 100 GHz DFB Comb Laser, at OFC 2023,” said Sylvie Menezo, CEO of Scintil Photonics. “Increasing computing capacity requires connecting larger networks of computing units with higher transmission rates. In order to achieve this with sustainable energy efficiency, fibre optic transmission links are used with multiple optical carriers multiplexed on one single fibre. We have succeeded in implementing a comb laser source with only 100 GHz spacing between each optical carrier. This offers at least twice the number of optical carriers compared to what appears to be available today and therefore enables doubling the transmission speed. Leading customers are currently evaluating our solution.”
