Artificial intelligence has a massive power problem that threatens to stall global progress. Enlightra just emerged from the shadows to solve it. The Swiss startup secured $15 million to replace inefficient copper wires with cutting edge lasers. This breakthrough promises to slash energy costs and turbocharge data transmission for future AI clusters.
Solving the copper bottleneck
Data centers are hitting a physical wall. The massive server farms that power ChatGPT and other AI models currently rely on copper cables to move data between chips. These copper wires generate immense heat and consume vast amounts of electricity. They limit how fast data can travel. This creates a bottleneck that slows down training for large language models.
Enlightra offers a way out of this trap. The company has developed a new type of laser technology that transmits data using light instead of electricity. This method is significantly faster and runs much cooler than traditional copper.
Why this matters for the AI industry:
- Speed: Light moves data faster than electricity moves through copper.
- Heat: Optical links generate far less heat which reduces cooling costs.
- Scale: It allows data centers to grow without overwhelming local power grids.
Maxim Karpov is the co-founder and co-CEO of Enlightra. He noted that the world’s AI infrastructure is hitting the limits of copper. He believes their lasers unlock a new level of energy efficient connectivity by turning light into the backbone of GPU communication.
This shift comes at a critical time. Tech giants are scrambling to find power sources for their expanding data centers. A technology that reduces power consumption at the chip level could save billions of dollars in operational costs.

Heavy hitters back the vision
The $15 million funding round proves that investors see huge potential here. The investment includes a mix of seed and pre-seed funding. Several high profile firms participated in the round.
Y Combinator is among the lead investors. This accelerator is famous for backing companies like Airbnb and Dropbox early on. Their involvement signals strong confidence in the team and the technology.
The full list of key investors includes:
- Y Combinator
- Runa Capital
- Pegasus Tech Ventures
- Protocol Labs
- Halo Labs
These investors are betting on a hardware revolution. Software has dominated the AI conversation recently. However, the hardware that runs that software is in desperate need of an upgrade.
Enlightra is not just a concept on paper. The startup is a spin off from the Swiss Federal Institute of Technology in Lausanne. The team has spent years refining the physics behind these lasers. They are taking deep science and turning it into a commercial product.
Magic inside the tiny chip
The core innovation is something called a “multiwavelength laser” or a comb laser. Traditional optical systems often require a separate laser for each color of light. Each color acts as a separate channel for data. This takes up space and consumes power.
Enlightra has managed to consolidate many lasers into a single source. A single chip can generate multiple distinct wavelengths of light. Imagine a single instrument playing an entire chord instead of just one note.
John Jost is the other co-founder and co-CEO. He explained that using additional wavelengths allows optical fiber networks to operate closer to their full capacity.
Comparison of Data Transmission Methods:
| Feature | Traditional Copper Links | Enlightra Optical Lasers |
|---|---|---|
| Medium | Electricity over metal | Light over fiber |
| Heat Output | High | Very Low |
| Bandwidth | Limited by distance | Extremely High |
| Scalability | Difficult due to power | Highly Scalable |
This technology relies on standard silicon photonics fabrication. This is a crucial detail. It means the chips can be made using existing manufacturing processes. They do not require a completely new type of factory to build.
The company has already developed 8-channel and 16-channel lasers. These align with what current AI chip makers need. They have reported error free data transmission in their tests. This reliability is essential for mission critical data centers.
Road to mass production
The funding will help the team move from the lab to the factory floor. However, this transition will not happen overnight. Deep tech hardware takes time to perfect and scale.
Enlightra plans to begin pilot production in 2027. This timeline aligns with the expected release of next generation AI hardware. Chip designers are currently planning architectures for the end of the decade. They need to know that the optical interconnects will be ready.
The vision extends beyond just AI servers:
- Subsea Cables: Improving the efficiency of internet traffic across oceans.
- Consumer Tech: Potential for faster chip-to-memory speeds in home computers.
- Space Communication: Robust data links for satellites and deep space missions.
- Quantum Computing: Providing the precise light sources needed for quantum processors.
The immediate focus remains on the data center. The demand for compute power is doubling every few months. The physical limitations of copper are becoming a hard ceiling.
Enlightra is positioning itself to break that ceiling. By decoupling performance growth from energy increases, they provide a path forward. The industry needs to scale up without melting down the planet.
This $15 million injection gives them the runway to hire talent and finalize designs. The race to build the infrastructure for the AI age is on. Enlightra has just secured its place at the starting line.
Current systems are gasping for efficiency. This startup offers a breath of fresh air. Or rather, a beam of light.
The tech industry is watching closely. If Enlightra succeeds, the inside of a server rack in 2030 will look very different from today. It will be cooler, faster and powered by light.
Enlightra has stepped out of stealth mode with a clear mission and a loaded war chest. The team is tackling one of the biggest physical hurdles in computing history. Their success could determine the speed at which artificial intelligence evolves in the coming decade. We will have to wait until 2027 for the pilot, but the promise is undeniably bright.
