Photonics – the field that supports light-based systems for data processing – has a bright future, as the rise of artificial intelligence requires better computing performance, but it has not yet been fully applied to a new generation of chips. German startup Achitonix He hopes to change that. It has raised a seed funding round of €6 million (about $6.33 million) to deliver on that promise, TechCrunch exclusively reveals.
While many companies work with photonics on cross-sectional issues or point solutions that blend electronics and photonics, Aketonics – whose name is a portmanteau of My brotheran Egyptian hieroglyph meaning “horizon”, and photonics – explicitly aimed at building a general-purpose chip.
“General purpose” in this context means chips that can be used for all kinds of software tasks and applications. Since Aketonics takes an all-optical approach that will also be digital and compatible with today’s workloads, unlike analog approaches, it could be particularly useful in environments that require high real-time performance, such as networking, avionics, and aerospace.
Aside from speed, energy efficiency is another aspect in which photonics can help – one that is increasingly linked to geopolitics, as is the case with chip sovereignty. “For us, the most interesting part is that we have a very diverse supply chain,” Michael Kisner, co-founder and CEO, told TechCrunch.
Aketonics could potentially make its general-purpose chips anywhere, giving companies access to locally sourced high-performance computing – if It works. This is a big “if”; Or more precisely, “when.”
Most observers agree that photonics will make its way into chips, but French venture capital firm Daphne, for example, recently said it Wouldn’t invest in general purpose chips at the moment.
while lite materiala photonics company that initially focused on chips, then focused on interconnection and achieved great success, resulting in faster data transfer between central processing units (CPUs) and graphics processing units (GPUs) within data centers.
While it’s still a long way off for some, Matterwave Ventures, the venture capital firm that led Aketonics’ new round, believes the time is right to apply fully optical technology to general-purpose calculations. “For us, we felt like there were enough things coming together to make this a reality,” Silvio Aposto, the school’s principal, told TechCrunch.
This will take some time, but perhaps not as much as some think; Aketonics plans to deliver its first commercial product to customers mid-next year. Kissner is confident that its feasibility is already proven thanks to a previous funding round from deep-tech firm Runa Capital in 2023. “Our big goal was to show that you can do general-purpose computing using just optics, and that’s something we’ve now ‘demonstrated,'” he said. .
The key to Ahetonics’ approach — and what makes it possible, according to Aposto — is rethinking architecture from first principles.
“People think you need billions of (phototransistors),” Kesner added. “But with the right architecture, that won’t happen.” For example, the company explained In a recent paper How can it do without the usual optimization that the likes of AMD, Intel and Nvidia have applied to current generation chips.
This also makes the development process cheaper than regular chips, hence the relatively small circular size of the chipmaking business. Aketonics said most of the initial funding will go towards increasing headcount to 30 people as the team works to deliver prototypes to customers. “For us, this is actually a significant amount of money,” Kesner suggested. “In our world, you can design a chip for 50,000 euros.”
Cheaper costs and a local supply chain are two big differences compared to AI-based semiconductors; Kissner seems genuinely puzzled that the trillion-dollar “aluminum industry” relies on chips made in geopolitically troublesome regions. Clearly, Aketonics’ alternative stance has resonated with investors. “They really support our mission of creating this semi-democratic European version of high-performance computing,” he said.
With all that said, questions remain about the commercial demand for HPC, and whether it can be better served by integrated photonics for specific use cases. But for Akhetonics, competitors like LightSolverAll optical chips are the best answer.
