Coherent Corp. is gearing up for a big showcase at OFC 2026 in Los Angeles. They’re rolling out a lineup of co-packaged optics (CPO) demos that cover silicon photonics, indium phosphide (InP) lasers, VCSELs, and some pretty advanced packaging tricks.
This post gives you a quick rundown of the announcements, what you might see at Booth 1401, and why these demos could shake up next‑gen data center architectures—especially with AI and high‑performance computing (HPC) workloads ramping up like crazy.
Coherent’s OFC 2026 Demonstrations: What to Expect
At OFC 2026, Coherent will show off several new breakthroughs in co-packaged optics. One highlight is a 6.4T (32×200G) socketed CPO built on silicon photonics, paired with Coherent’s External Laser Source (ELS) module that uses high‑power InP continuous‑wave lasers.
They’re also bringing a multimode socketed CPO with high‑speed VCSELs, plus an InP modulator on silicon running at 400G alongside a 400G‑per‑lane InP modulator array. All of these demos point toward a push for higher lane speeds and more scalable CPO setups.
Coherent’s lineup really shows off their cross‑platform chops with indium phosphide lasers, silicon photonics, VCSELs, and advanced packaging. The company sees its portfolio as a way to unlock next‑generation data center architectures that can actually keep up with the bandwidth demands AI and HPC are throwing at them.
With their vertically integrated tech stack and some serious supply‑chain reach, Coherent wants to help customers try out different CPO approaches—whether it’s scale‑out or scale‑up. If you’re heading to OFC 2026, swing by Booth 1401 to check it all out.
Technology Deep Dive: CPO Across Platforms
The 6.4T, 32×200G socketed CPO on silicon photonics goes for a high‑density, optics‑in‑a‑socket style. It’s meant to boost per‑rack bandwidth and maybe even simplify systems a bit.
The ELS module is a big part of this demo, packing high‑power InP‑based laser light into a small, tidy package. By bringing InP lasers together with silicon photonics, Coherent wants to mix the reliability and efficiency of InP sources with the scale and manufacturability that silicon brings to the table.
The multimode socketed CPO leans on high‑speed VCSELs for flexible mode setups and, with any luck, lower packaging costs. Even so, it still delivers plenty of bandwidth without eating up a ton of space.
Meanwhile, the InP modulator on silicon at 400G shows a clear path toward bigger lanes and richer modulation formats. That 400G‑per‑lane InP modulator array looks ready to scale as data center needs keep growing.
It’s pretty clear these demos show Coherent’s knack for cross‑platform integration—they’re pulling together InP lasers, silicon photonics, and VCSELs with some clever packaging. The company is betting this portfolio will help data centers adapt, since operators might need different CPO approaches depending on workload, density, or even what’s happening in the supply chain.
Why This Matters for Data Centers, AI, and HPC
Coherent’s OFC 2026 program really shows how the company wants to support a range of optical architectures as networks grow to handle AI and HPC. They’re putting both high-density silicon photonics solutions and InP-based modulators on display.
This signals a flexible, scale-out and scale-up approach that can adapt to all sorts of data center needs. Coherent draws on its vertical technology stack and broad supply chain experience to help customers reduce risk and move faster when deploying new CPO configurations.
Some folks in the industry might see these demos and think the data center of the near future will mix and match CPO approaches, each one tuned for specific workloads or rack constraints. Combining high-density 6.4T options with modular 400G lanes could make networks more scalable and power efficient.
That’s going to matter more as AI models keep getting bigger and training eats up even more resources. Coherent is pushing a coherent optics ecosystem that supports multiple optical architectures—no one-size-fits-all path here.
This kind of flexibility, along with their strong supply chain and packaging skills, fits with where the industry’s headed: heterogeneous, multi-vendor optical networks in today’s data centers.
