Vector Photonics to present on PCSELs at ECOC


Paper will show how PCSELs can deliver data centre bandwidths of 800Gbs and over

Vector Photonics has been invited to present its paper, ‘PCSELs at multiple wavelengths for high-bandwidth communications’ at the ECOC exhibition and conference in Basel, Switzerland, from the 19th - 21st September.

Calum Hill (pictured above), principle development engineer at Vector Photonics will present the paper. He said: “Hyperscale datacentres require at least 800Gbs data transmission interconnects to keep up with growing demand for cloud services. This is at the limit of current, pluggable, optics technology. Vector Photonics’ PCSELs more easily enable co-packaged optics solutions, where the optical functionality is integrated onto the ASIC (application-specific integrated circuit) to improve overall system performance, whilst reducing system energy consumption and cost.

“The CW (Continuous Wave) PCSELs, required for these bandwidths, operate in the O-band as a high-power, seed laser for multiple data channels. Their surface emission gives far better power scaling and beam divergence than conventional solutions, as well as simpler silicon photonics fabrication. Furthermore, the structure of a PCSEL is not dependent on the base epitaxy used, allowing PCSELs to be made at multiple different wavelengths for different communication needs.”

Calum will present the Vector Photonics paper at the ECOC on 21st September 2022 at the 8th International Symposium for Optical Interconnect in Data Centres.
