PCSELs take ECOC stage

News

Solving data centre 800Gbps optical interconnect challenges

As data centres look to co-packaged optics (CPO) for delivering interconnects of 800Gbps and above, Vector Photonics says its all-semiconductor PCSELs are gaining increasing attention.

PCSELs are surface emitters. This is said to lead to produce better power scaling and beam divergence than conventional lasers, as well as simpler silicon photonics fabrication. PCSELs are not dependent on the base epitaxy used, allowing the flexibility to manufacture at different wavelengths, not only for multiple datacoms but also for telecoms and other CPO applications.

Following his presentation at ECOC’s 8th International Symposium for Optical Interconnects in Data Centres, Calum Hill, principal development engineer at Vector Photonics said: “The current, transceiver, optics technology used in data centres is at its limit and unable to keep pace with demand for cloud services. This is a critical moment for datacoms and one Vector Photonics PCSELs address.

"Our all-semiconductor PCSELs attracted a lot of attention and were seen as the foremost laser solution for 800Gbps optical interconnects and above."
