The promise is etched in a single, precise measurement: 9mm by 9mm. That’s the footprint of LightSpeed Photonics’ LightKonnect module, a square of silicon and optics meant to be soldered directly onto a circuit board, millimeters from the processor it serves [OFC Conference, March 2026]. The company’s bet is that this specific geometry is the practical next step for data centers straining under AI workloads.
LightSpeed Photonics, founded in 2021 and headquartered in Singapore, calls its approach “near-packaged optics” (NPO). It’s a middle path. Co-packaged optics (CPO) aims to embed optical engines directly into the processor package, while linear pluggable optics (LPO) are the mature, swappable standard. LightSpeed’s NPO sits between them: optics kept physically close to the application-specific integrated circuit (ASIC), soldered onto the same board, but not fused into the same package [PERPLEXITY SONAR PRO BRIEF, retrieved 2026].
The Goldilocks Geometry
The technical argument hinges on proximity and power. By placing the optical engine within a few centimeters of the ASIC, LightSpeed shortens the electrical traces that data must travel before being converted to light. The LightKonnect product line, announced in March 2026, delivers 400 gigabits per second from that 9mm square package [OFC Conference, March 2026]. For system designers, the appeal is in the integration: a solderable, surface-mount component fits into standard assembly processes, avoiding the exotic packaging techniques CPO requires. It’s a pitch for incremental revolution, using proven components like VCSELs to accelerate time-to-market and reliability [Crunchbase].
A Foundry-Lite Path to Market
LightSpeed Photonics operates as a fabless company, designing the silicon and optical systems but outsourcing manufacturing. The company’s strategy appears to be one of asset velocity: move quickly by leveraging existing semiconductor supply chains and foundry partnerships. This is reflected in its team build-out. The company has made a key commercial hire in Mahir Mehta, formerly Business Development Director for IoT at Intel, as its Chief Business Officer [Businessworld, 2023-06-06].
CEO Rohin Y is scheduled to speak on the “Practical Path Beyond CPO” at the OFC 2026 conference [OFC Conference, March 2026]. He also hosts the ‘First Principles’ podcast [Apple Podcasts]. Co-founder Ramana Pamidighantam is described as focused on enabling “industry connects” to scale the company [LinkedIn]. With a team of 11-50 employees split between Singapore and Hyderabad, India, LightSpeed is positioning itself at the intersection of global deep-tech ambition and Asian manufacturing prowess [LinkedIn].
Funding and the Competitive Field
LightSpeed has raised an estimated $6.5 million in a pre-Series A round, with pi Ventures leading and participation from Applied Ventures, 500 Global, and others [The Economic Times]. The company was also a participant in the Luminate accelerator program [Luminate].
| Selected Competitors in Optical Interconnects | Primary Approach | Notable Differentiator |
|---|---|---|
| Ayar Labs | Co-packaged optics (CPO) | Silicon photonics chips integrated with processors |
| Lightmatter | Optical computing & interconnects | Uses light for both computation and data movement |
| Celestial AI | Photonic fabric | Optical interconnect for chip-to-chip communication |
| LightSpeed Photonics | Near-packaged optics (NPO) | Solderable, board-level modules using VCSELs |
An honest look at the landscape reveals several pressure points for LightSpeed:
- The integration sell: Convincing conservative data center operators to adopt a new form factor requires proving reliability and total cost of ownership over pluggables.
- The scaling race: While capital-efficient, the fabless model means ceding some control over production timelines and yields to external partners.
- The proof milestone: Public announcements focus on product launches; the next critical signal will be named design wins or partnerships with major OEMs.
The company’s stated next steps are to commercialize its LightKonnect Fiber product and complete certifications for large-scale deployment [piventures.in].
