The phenomenon of light manipulation through photonics has emerged as a transformative technology with the potential to revolutionize computing systems. As demands for increased processing speeds and energy efficiency grow concurrent with the rapid rise of artificial intelligence (AI), the integration of photonic technology into chip design seems almost inevitable. Yet, many startups and established companies have only scratched the surface of what this field has to offer. One promising enterprise, German startup Akhetonics, aims to redefine the landscape of high-performance computing. Recently, Akhetonics secured a notable seed funding round of €6 million ($6.33 million) to take significant steps towards creating general-purpose photonic chips.
Akhetonics, with its name deriving from the Egyptian hieroglyph “Akhet,” meaning “horizon,” suggests a forward-thinking philosophy fundamental to its mission. The startup is laser-focused on developing a versatile chip architecture capable of handling diverse computational tasks. Unlike current technologies that tend to modify existing electronic solutions to incorporate photons, Akhetonics plans to create an entirely all-optical approach that is not only digital but also compatible with contemporary software workloads. This novel architecture positions Akhetonics to serve sectors that necessitate high-speed computations, including networking, avionics, and the aerospace industry.
The transition to all-optical computing represents a paradigm shift that could deliver significant performance benefits while addressing rising energy consumption concerns. In an age where geopolitical factors increasingly influence supply chains, the enhanced efficiency brought forth by photonic technologies could play a crucial role in achieving chip sovereignty, a term that reflects a manufacturer’s ability to operate independently in a volatile world market.
Diversity in the Supply Chain
Co-founder and CEO Michael Kissner emphasizes the significance of a diverse supply chain for Akhetonics. The ability to manufacture chips locally could position companies to harness high-performance computing capabilities without being beholden to international partners, particularly those situated in politically unstable regions. The company’s aspiration to democratize access to advanced computing resources resonates well with current trends focusing on regional autonomy in technology.
However, while the prospects are compelling, there remains skepticism in the investment community. For example, French venture capital firm Daphni has indicated hesitancy to finance general-purpose photonic chips at this stage, citing alternative methods that are currently attracting more traction—like integrated photonics and interconnects. The field is rife with challenges, as illustrated by Lightmatter, a photonics company that pivoted away from chips to focus on faster data transfer solutions between existing CPU and GPU configurations.
Yet proponents like Matterwave Ventures, which recently funded Akhetonics, openly advocate for the validity of an all-optical approach to general-purpose computing. Silviu Apostu, a principal at the venture firm, believes that the present moment is ripe for such developments. With Akhetonics aiming to release its first commercial product within a year, there is a palpable excitement in the air.
Kissner and his team are strategically innovating by reexamining chip design principles from the ground up. Their research suggests that by leveraging an optimized architecture, the agency can drastically reduce the number of required optical transistors. This has profound implications for cost-efficiency and could enable the startup to undercut traditional chipmakers like Intel and AMD, who have historically relied on heavy optimization models that inflate development costs.
The recent seed funding will primarily be allocated towards expanding Akhetonics’ workforce from its current size to 30 employees, a modest but crucial step in their quest to introduce prototypes. Given that chip design expenses can be contained within a reasonable budget—about €50,000 per chip—Kissner maintains that the investment allows them to scale effectively whilst overcoming the initial hurdles typical of a nascent company.
Ultimately, alongside a cheaper local supply chain, Akhetonics’ strategic positioning emerges as a viable alternative to the dependency on chips manufacturing in regions burdened with geopolitical strife. The support from investors manifests a mutual vision of fostering a more accessible, democratized approach to high-performance computing that aligns with current demands for innovation.
As Akhetonics navigates the complexities of developing all-optical chips, it faces questions regarding the commercial viability of high-performance computing as a sector in its own right. While the sceptics highlight the potential advantages of integrated photonics tailored for specific applications, Akhetonics remains resolute in its belief that an all-optical solution is the answer for a spectrum of computational challenges. With the company committed to proving its model and executing its vision, the outcome of this endeavor could herald a new era in computing.
