Balerion Principal Emerson Garnett sits down with Cailabs Co-Founder & CEO Jean-François Morizur to discuss optical communications and ground infrastructure. Cailabs develops optical ground stations using its multi-plane light conversion technology to mitigate atmospheric turbulence and enable high-bandwidth laser communications between satellites and Earth. Jean-François discusses the company’s origins, growing demand for optical communications across defense and Earth observation, scaling production of its TILBA ground stations, transportable systems, interoperability, and the role optical communications could play alongside traditional RF infrastructure.

00:00 – Origins of Cailabs and multi-plane light conversionJean-François describes how technology developed during his PhD led to a patent for multi-plane light conversion, or MPLC. After leaving academia for BCG, interest from the telecom industry brought him back to commercialize the technology and eventually build Cailabs.

01:52 – Solving atmospheric turbulence for optical communicationsJean-François explains why satellite-to-ground laser communications are more difficult than satellite-to-satellite links. Atmospheric turbulence distorts light traveling through the atmosphere, and Cailabs uses its MPLC technology to mitigate those effects within its optical ground stations.

04:23 – Demonstrating product-market pullCailabs demonstrated optical links with Kepler satellites using SDA-compatible terminals at a time when reliable optical space-to-ground communications remained a challenge. Jean-François describes these demonstrations as an important validation of the company’s technology and a driver of subsequent customer engagement.

07:02 – Lessons from BCG and the importance of execution speedJean-François discusses how his time at BCG changed his approach to building a technology company, particularly the importance of making good decisions quickly. He also explains why developing operational optical ground infrastructure requires a dedicated engineering organization rather than a small experimental team.

11:03 – Demand from defense, sovereign space, and Earth observationDifferent customers are adopting optical communications for different reasons. Earth observation operators need to move increasingly large datasets to the ground faster, while defense users value optical systems for their different detection, interception, and jamming characteristics compared with RF.

14:43 – How optical communications fit into existing SATCOM procurementJean-François explains that optical and RF ground communications are increasingly being considered within the same procurement processes. Because many SATCOM organizations are built around RF expertise, Cailabs also spends time educating customers about optical systems and their current level of technical maturity.

18:05 – TILBA and scaling ground-station productionCailabs’ TILBA platform integrates the company’s technology into a complete optical ground station. Jean-François discusses plans to scale production toward 50 systems per year and the manufacturing, supply-chain, quality, and design changes required to move from low-volume production to industrial scale.

21:02 – Interoperability and distributed ground networksGround infrastructure can accommodate differences in modems and customer standards more easily than hardware already deployed in orbit. Jean-François discusses increasing convergence around interoperable specifications and the tradeoffs between ground-station performance, cost, location, and geographic proliferation.

25:06 – Deployment timelines and transportable ground stationsCailabs can target ground-station deployments in less than nine months, with site selection and permitting increasingly becoming important constraints. Transportable ground stations can reduce those limitations while also creating additional applications for defense customers.

27:17 – High-bandwidth downlinks for Earth observationJean-François explains how optical links operating at 10 Gbps, with potential upgrades to 100 Gbps, can allow Earth observation operators to downlink substantially more imagery during a single pass. Faster downlinks can reduce the delay between collection and analysis and may change how satellites are designed to collect and store data.

29:57 – AI, edge processing, and growing bandwidth requirementsAlthough onboard processing could reduce some downlink requirements, Cailabs is seeing customers—particularly within the intelligence community—continue to demand access to raw data. Jean-François argues that AI and increasingly data-intensive space systems may therefore increase rather than decrease demand for high-capacity optical links.

31:24 – Expanding manufacturing in Europe and the United StatesCailabs currently has capacity to manufacture approximately 12 optical ground stations per year, with its new facility designed to support as many as 50. Jean-François also discusses plans to establish U.S. manufacturing capability to address sovereignty and domestic-production requirements from American customers.

33:27 – When optical communications become routine SATCOM infrastructureJean-François expects optical communications to become increasingly routine as customers gain operational experience with the technology. Defense applications may adopt optical systems more quickly where low probability of detection and interception or resistance to jamming are important, while commercial adoption will also depend on bandwidth economics and access to RF spectrum.

36:30 – Ground-to-ground optical communicationsCailabs is also applying its atmospheric turbulence technology to terrestrial line-of-sight communications. The company has demonstrated links over distances of approximately 40 kilometers, with potential defense applications including communications in radio silence as well as ship-to-ship and ship-to-shore links.

39:27 – Optical communications as strategic and commercial infrastructureJean-François expects optical communications to develop similarly to RF, with some systems serving national-security applications and others becoming broadly available commercial infrastructure. Proliferated optical ground stations could also provide NATO countries with additional communications resilience if traditional links are disrupted or jammed.

41:41 – Cailabs’ next phase of expansionJean-François previews upcoming developments around transportable systems, the opening of Cailabs’ new production facility, and plans for U.S. manufacturing. He describes the optical ground market as entering a period in which multiple developments are beginning to accelerate simultaneously.

43:17 – China, NATO, and the geopolitics of optical communicationsThe conversation closes with the strategic importance of optical communications. Jean-François discusses ongoing Chinese development in the field and argues that the United States and Europe need to work together to maintain strong optical communications capabilities across NATO.
