Photonic Technology: The Light-Speed Breakthrough Inside AI Data Centers

The terms “photonic” and “photonics” are used interchangeably in Jason Bodner’s Accelerated AI presentation, and both refer to the same concept: using light instead of electricity to transmit data. The distinction is mostly grammatical. “Photonics” is the field of study. “Photonic” is the adjective applied to the components, chips, and systems that use the technology. When Bodner talks about a “photonic chip” or a “photonic breakthrough,” he is referring to the same technology transition he describes as “photonics.”

The important thing is not the terminology but the technology. And the technology is real, it is shipping, and it is backed by billions of dollars in investment from the largest companies in the world.

What Photonic Technology Does

Inside an AI data center, thousands of GPUs need to communicate with each other simultaneously. The data currently moves over copper wires. Electrons in copper travel at less than 1 percent of the speed of light. They generate heat, consume significant power, and cannot keep up with the bandwidth demands of modern AI workloads.

Photonic technology replaces copper with light. Light travels at 124,000 miles per second. It carries far more data, barely uses power, and does not generate the heat that copper does. Bodner says this makes AI “100 times faster and 100 times more energy efficient.” That is a significant claim, but the physics is straightforward. Nothing in the known universe moves faster than light.

The Structural Evidence

The investment in photonic technology is not speculative. It is strategic deployment by the largest players in the industry:

  • Nvidia has invested over $7 billion in photonic companies and partnered with Corning to build three optical factories in the United States.
  • AMD is building a $280 million photonic research hub.
  • Broadcom debuted the industry’s first 400G optical chip, which converts electrical signals to light.
  • Ayar Labs raised $500 million from ARK Invest and Sequoia Capital.
  • Google and Microsoft are backing nEye, which raised $80 million.
  • Bill Gates has personally invested over $200 million in two photonic companies.
  • The Optical Interconnect Alliance includes Nvidia, AMD, Broadcom, Microsoft, Meta, and OpenAI.

These are the kind of capital deployments that happen when the largest companies in the world see a technology shift coming. For more on the alliance, see our optical interconnect article.

The Acceleration Curve Framework

Bodner frames the photonic transition inside what he calls the Acceleration Curve, a three-phase pattern that has played out twice before:

Phase 1: A technology explodes onto the scene. (Internet in the 1990s, smartphones in 2007, AI today.)

Phase 2: The technology hits a wall. (The “World Wide Wait” for the internet, bandwidth strain for smartphones, the copper bottleneck for AI.)

Phase 3: A light-speed breakthrough smashes through the wall. (Fiber optics for the internet, fiber for mobile networks, photonics for AI.)

During the internet transition, companies like Equinix rose 37,000 percent and Netflix rose 188,471 percent. During the smartphone transition, Monolithic Power rose 17,000 percent. Bodner argues that the photonic transition for AI will be even bigger because AI is a larger market than the internet or smartphones. For more on the pattern, see our copper to fiber article.

Broadcom: The Free Ticker

Bodner reveals Broadcom (AVGO) for free in the presentation. Broadcom is at the center of the photonic transition because it designs custom AI silicon for OpenAI, Meta, Anthropic, and Google, builds the networking switches that let AI chips communicate, and debuted the industry’s first 400G optical chip. Broadcom’s AI revenue was $10.8 billion last quarter, up 143 percent year over year.

The Three Bonus Picks

Behind the $179 paywall, Bodner identifies three smaller companies with higher upside potential. One is described as a pure photonic play that moves data as light between data centers across cities and states, with a new product that cuts networking power use by 70 percent and over $6 billion in sales. Another builds parts that turn electrical signals to light inside AI clusters and was called “the next trillion-dollar company” by Jensen Huang. The third is a secret weapon inside every major AI data center with two of the three biggest AI spenders as customers.

These are the picks Bodner believes could deliver the kind of returns that the fiber-optic boom produced in the 1990s. The risk is higher because these are smaller companies, but so is the potential upside.

Considerations

Photonic technology is a genuine engineering discipline with real applications in AI data centers. The transition from copper to light is already underway. The risks are timing and competition. Multiple companies are investing heavily, and it is not yet clear which will dominate the next generation of optical components. Bodner acknowledges this: “I don’t always get it right.”

The right approach is to understand the technology, follow the capital flows, and use research like Bodner’s as one input into your decision-making process. If you want to explore the full thesis, you can access the Accelerated AI presentation through Brownstone Research.
