As AI infrastructure scales, most of the strain now falls on the connections between chips rather than the chips themselves: copper simply can't carry that much data at a power cost anyone can afford anymore. Drumbeat Capital's 2026 Deep Tech Report points to one answer to that inside a single rack: packaging the optical engine directly onto the compute silicon, a shift the report notes is already moving from research into early production. The same pressure shows up one layer further out too, in the scale-across links between racks and between data centers, built for distance, now being asked to carry AI-scale bandwidth instead. That's the layer our photonic circuits operate in: real-time monitoring and signal management built for higher capacity and simplified infrastructure, already shipping into that market rather than sitting in a research pipeline. Shipping inside the AI infrastructure customers are already building is a harder test than performing well in a lab: it's the one that actually decides whether any of this reaches production.

Optical channel monitoring sounds like a background function, until a channel drifts in a live DWDM network and nobody notices until it's already affecting traffic. That's the problem our nanoOCM is built to solve: real-time visibility into every channel, in a chip-scale footprint. We've already shown that four monitoring channels fit in the same space as one. The next step is bringing this 4-port capability into a standard QSFP package. Because our underlying nanoOCM technology is the smallest on the market, we are uniquely able to fit a flex-grid channel monitor into a pluggable form factor. Now, we have extended that plug-and-play functionality from a single-port module to a full four-port solution. A QSFP package means no new sockets, no redesigned line cards, and no dedicated integration projects. Because it's MSA-compliant, it slots directly into network equipment already in the field. Getting to "just plug it in" is usually the harder engineering problem, not the easier one. Four ports in one module also means one object doing the monitoring job that used to take four—resulting in less hardware, less cabling, and less rack space for the same total visibility. We'll have more to share as this moves from lab bench to shipping hardware. Integrated photonics, across markets. #PhotonPath #IntegratedPhotonics #Photonics #OpticalNetworking #nanoOCM

Innovation becomes stronger when different perspectives are part of the same conversation. For Antonio Barba, software engineer at PhotonPath, that means being part of a wider process, one where software, hardware, photonics and product development stay in constant conversation with each other. At PhotonPath, that exchange happens every day, across teams and areas of expertise, while building integrated photonics technology for telecom networks and AI data center infrastructure. For Antonio, it's a chance to keep expanding his own perspective, watching complex technology turn into real solutions through collaboration, not individual expertise alone.

Working in an international team means learning that there is never just one way to look at things. At PhotonPath, different cultures, backgrounds and experiences meet every day: in conversations, in decisions, in the way we collaborate and support each other. It means listening to different points of view. Making space for different ways of communicating. Learning from perspectives that may not be the same as yours. And growing together through that difference. Our team is made of people who bring not only their expertise, but also their stories, their habits, their languages and their way of seeing the world. And this is what makes the workplace richer. Different cultures bring different questions. Different experiences bring different approaches. Different perspectives help us build better solutions. For us, multiculturalism is not something to mention only when talking about company culture. It is something we experience in the small moments of everyday work: when ideas are shared, when challenges are discussed, when people learn from each other and when a common direction is built together. As PhotonPath grows, we want to keep building a workplace where people can contribute not by fitting into one single model, but by bringing their own point of view to a shared mission.

In a dense optical network, capacity is only half the story. The other half is being able to see what that capacity is actually doing. As DWDM and DCI infrastructures get denser and more dynamic, operators need real-time visibility across the spectrum to catch power drifts, spot variations and troubleshoot before they turn into outages. That's what PhotonPath's nanoOCM is built for: an ultra-compact Optical Channel Monitor for high-resolution spectral analysis in DWDM networks. C-band monitoring, 15 GHz resolution bandwidth and a 500 ms scan time, in a footprint that drops straight into ROADMs, optical line systems and DCI. Reliable optical infrastructure starts with being able to see it clearly. Integrated photonics, across markets. #PhotonPath #IntegratedPhotonics #OpticalNetworks #Photonics #DeepTech

Getting a photonic platform to perform well is one milestone. Getting it to perform exactly the same way, run after run, at volume, is another and turns out, that's the harder half of the job. That's what scaling Oxyn with XIVER is about. We're transferring manufacturing of our proprietary integrated photonics platform to XIVER's advanced 200 mm wafer infrastructure: competitive lead times, repeatable top-quality results and large production capacity. For telecom and datacom applications, that means building on a technology designed not only for performance, but for repeatability and scalability too. That's what scaling integrated photonics actually requires: technology built to be manufactured reliably, produced at scale, and deployed across markets.

Optical systems keep being asked to do more with less space. In applications like AI data centers, that means higher density of optical functions packed into every new generation of hardware. In telecom networks, it means more channels and more bandwidth without more rack space. Either way, traditional architectures reliant on discrete building blocks and optical components coupled together have hit a physical wall. Oxyn is built to close the gap: PhotonPath’s proprietary integrated photonics platform condenses an entire assembly of discrete optical components and functions into a single, high-performance chip. Fewer parts sounds like a size story, and it is one. It's also an assembly story: every connection between separate components is one more place where alignment can drift or things can fail under stress. Cut the parts, cut those points of failure too. The part that matters most: none of this comes at the cost of optical performance. Oxyn is engineered as a seamless replacement for the discrete architecture already doing the job today: same performance, less space, assembly that holds up. Scalable optical systems run on photonics engineered for integration from the start. Integrated photonics, across markets. #PhotonPath #IntegratedPhotonics #Photonics #Oxyn #DataCenters

A PhotonPath Town Hall is when the whole team gets in one room to see where the business is heading, talk through what's moving in the market and step back to look at what we're building together. Our latest quarterly session covered company progress, market developments and the next steps on our roadmap. We also ran a team retrospective, an honest look at what's working and where we can do better. And we were glad to welcome Maddalena Binda to the team. Welcome aboard, Maddalena! These sessions are a good reminder of how a deep-tech company actually grows: on its people as much as on its products. Different backgrounds and expertise pulling toward one mission, making integrated photonics more scalable, deployable and ready for the real world. Thank you to everyone who contributed to the discussion and continues to help move PhotonPath forward. #PhotonPath #LifeAtPhotonPath #Photonics #IntegratedPhotonics
