New laser technology can reduce Danish energy consumption by 10 per cent

"We’ve already demonstrated energy-efficient, chip-based lasers with unprecedented stability, and we therefore expect that, with the innovation platform in the project, we can rapidly get this advanced, cost-effective technology out and make a difference on the internet of the future," says Assistant Professor Nicolas Volet (on photo).

A Danish research collaboration called GreenCOM aims to address the increasing energy consumption and cybersecurity challenges of the internet while enabling digital solutions that are intelligent, secure, and energy-efficient. The collaboration involves 18 companies, two universities, two GTS institutes, and two industrial associations. The project aims to develop a digital infrastructure that can transport larger volumes of data faster, cheaper, more securely, and in a greener manner than current systems. The interdisciplinary research team at Aarhus University will focus on maturing chip-based laser technology for the internet, with a focus on energy-efficient and stable laser solutions using integrated photonics. The project, supported by Innovation Fund Denmark with DKK 40 million (EUR 5.4 million), has the potential to reduce Denmark's total energy consumption by up to 10% while enabling increased digitalization. The innovation platform will involve diverse partnerships across the Danish ICT industry to deliver solutions that contribute to the overall goals of GreenCOM.
