OpenLight turnkey InP-on-silicon platform

This is a distribution advantage as much as a manufacturing one. OpenLight is turning a hard supplier onboarding problem into a product. Instead of a module maker negotiating process access, qualifying a fab, and proving the design will survive production, it can use OpenLight’s qualified PDK, tape out on Tower’s PH18DA line, and get tested chips back in 8 to 12 weeks with first article performance support.

• For many optics companies, the real bottleneck is not drawing the PIC, it is getting foundry access and process confidence. OpenLight bundles both. Its model is PDK license up front, design services during development, then royalties once customer chips move into volume production.

• The Tower link matters because OpenLight’s key differentiator, InP active devices on silicon, is already built into a commercial wafer flow. OpenLight and Tower demonstrated 400G per lane modulators on PH18DA, and OpenLight later completed GR-468 qualification for lasers, modulators, and photodiodes on that process.

• This also explains the contrast with other models. Intel mainly uses its silicon photonics platform inside its own systems and has shipped more than 8 million PICs, while GlobalFoundries sells a foundry platform directly. OpenLight sits between those poles, independent like a platform company, but packaged to feel turnkey for customers.

The next step is for OpenLight to become the default path for companies that need custom optics but do not want to build foundry operations as a core capability. As more designs move from prototypes to production orders on PH18DA, the company can compound from software like design wins into royalty bearing manufacturing volume.
