Traditional processors from the likes of Intel, AMD or Nvidia have well-known limitations in terms of speed, energy efficiency and electromagnetic interference. For example, foundational chipmakers like TSMC and Samsung are currently careers move to the 3nm process for clients like Apple and Nvidia.

Meanwhile, photonics is becoming a bigger sector as chipmakers seek faster solutions. Unlike electrons, the wavelengths of light do not interact, which means it can create parallel data streams within a chip. The size of the global photonics market was valued at $630 billion in 2021 and is My dear to reach an expected value of USD 1.1 trillion by 2030, for example.

Commissioning of all-optical processors achaetonicthink you have the answers.

It has now raised €2.3 million in early-stage funding led by deep-tech investors Runa Capital. Other investors include Interface Capital, Rheingau Founders, Thomas Pirschke (co-founder of Trade Republic) and Marie Tai (head of Possible Ventures).

Akhetonics claims to have multiple prototypes of the optical transistor and the basis of a processor design.

Its competitors include light matter, LightIntelligence, optalysis. The Berlin-based startup says its all-optical processors will have higher bandwidth and faster speeds with greater efficiency and information density than electronic ones.

Their goal is a full-scale optical CPU, with a full prototype by 2024.

“Our mission at Akhetonics is to create an entirely new computing technology: the world’s first all-optical general purpose CPU. We are driven by an ambition to push the boundaries of what is possible in computing,” said Michael Kissner, CEO of Akhetonics in a statement. “The funds raised will play a critical role in bringing our vision to life, accelerating our research and development efforts, and enabling us to integrate our innovative technology into our first product.”

Dmitry Galperin, General Partner at Berlin-based Runa Capital, added: “We see tremendous opportunities in Akhetonics’ innovative approach to all-optical processing. Its technology has the potential to revolutionize multiple industries, from high-performance networking and security hardware to quantum computing.”
