Europe to Secure Space Communications Using Laser Technology
Delft, Wednesday, 23 September 2026.
The European Space Agency selected Dutch research agency TNO to develop secure satellite communications using advanced light-based laser technology and photonic chips, strengthening Europe’s digital sovereignty.
The Photonics Revolution in Space
This cutting-edge space initiative falls squarely within the domain of photonics, a branch of technology focused on the manipulation and transmission of light [1][2]. Rather than relying on traditional radio-frequency bands, which are increasingly congested and susceptible to electronic jamming, this innovation utilizes Photonic Integrated Circuits (PICs) [1][2][GPT]. PICs function similarly to traditional electronic microchips but use photons (light particles) instead of electrons to process and route information [GPT]. By integrating these advanced light-based chips into next-generation optical terminals, satellites can establish incredibly fast, high-bandwidth, and highly secure communication links across space and directly to ground stations [1][2].
Key Players and Leadership
The organization leading this technological leap is TNO, a prominent research agency based in the Netherlands [1]. On September 17, 2026, TNO announced its selection by the European Space Agency (ESA) to head the system design and technical feasibility validation for these PIC-driven optical terminals [1]. The initiative is closely supported by the Netherlands Space Agency (NLSA) and involves FSO Instruments, a Dutch partner specializing in commercializing optical satellite communication equipment [1]. Kees Buijsrogge, the Director of Space at TNO, is spearheading the effort, advocating for home-grown European innovations that secure critical data infrastructure [1].
Harnessing Light for Secure Space Connectivity
To understand how this technology works, one must look at how laser satellite communication (LaserSatcom) operates in orbit. Traditional radio waves disperse widely as they travel, making them easier to intercept or disrupt [GPT]. In contrast, the PIC-powered terminals developed by TNO will generate highly focused, narrow laser beams to transmit data directly between satellites in Low Earth Orbit (LEO) and optical ground stations [1][2][GPT]. This point-to-point light transmission ensures that the data pathways remain virtually immune to interception, providing an unprecedented level of security for military, government, and commercial operations [1][2][GPT].
Unlocking Unprecedented Bandwidth and Security
The benefits of this photonics innovation are multifaceted, addressing the core limitations of modern space infrastructure. By utilizing light instead of radio frequencies, the system unlocks massive bandwidth capabilities, enabling the rapid transfer of complex Earth observation data and secure governmental communications [1][2]. Furthermore, because PICs consolidate complex optical assemblies onto a single microchip, the resulting terminals are significantly lighter, more compact, and consume less power than conventional communication payloads [2][GPT]. This makes them highly suitable for the stringent physical constraints of LEO satellite constellations [1][2].
Strengthening European Sovereignty and the IRIS² Timeline
This project is a critical component of Europe’s broader push for technological sovereignty [1]. On September 16, 2026, in Madrid, Spain, Laurent Jaffart, representing ESA’s Programme Related to EU Secure Connectivity, signed 18 pivotal contracts—including the agreement with TNO—to advance the LEO layer of the IRIS² (Infrastructure for Resilience, Interconnectivity, Security and Satellite) secure multi-orbital constellation [5]. These dual-use communication infrastructures are designed to protect European data from external vulnerabilities [1][2]. According to ESA’s roadmap, initial service deployment for the IRIS² network is expected to commence by mid-2027, with the ultimate goal of achieving Full Operational Capability (FOC) by December 31, 2027 [5].
