ALTER TECHNOLOGY TUV NORD SA

Their core work

Alter Technology (part of TÜV NORD Group) is a Spanish company specializing in space-grade and high-reliability optoelectronic components, detectors, and photonic systems. They provide testing, qualification, and integration expertise for advanced semiconductor devices used in space missions, LiDAR systems, and critical infrastructure. Their work spans from avalanche photodiodes for greenhouse gas monitoring satellites to photonic payloads for high-throughput satellite communications and cybersecurity solutions for electrical power nanogrids.

What they specialise in

How they've shifted over time

Their early H2020 work (2018-2019) was firmly rooted in space detector hardware — HgCdTe avalanche photodiodes for Earth observation, GaN-based thermal packaging for satellite payloads, and CMOS readout circuits. From 2019 onward, they broadened into photonic integration (optical phase arrays, VCSELs, digital photonic payloads) and terrestrial applications like 3D sensing for Industry 4.0 and smart buildings. Their most recent project (ELECTRON, 2021) signals a strategic pivot toward cybersecurity and power grid resilience, moving beyond their pure hardware heritage.

They are expanding from pure space hardware into dual-use photonic technologies and critical infrastructure security — expect growing interest in terrestrial applications of their space-proven expertise.

How they like to work

Alter Technology participates exclusively as a consortium partner, never as coordinator, which is consistent with their role as a specialized technology provider contributing specific component-level expertise to larger system projects. With 83 unique partners across 21 countries in just 5 projects, they operate in large, internationally diverse consortia (averaging ~17 partners per project). This broad network and specialist positioning makes them easy to integrate into new consortia where advanced detector, photonic, or qualification expertise is needed.

They have collaborated with 83 distinct partners across 21 countries through just 5 projects, indicating involvement in large pan-European consortia. Their network is heavily weighted toward space and photonics communities across Western and Southern Europe.

What sets them apart

As part of the TÜV NORD Group, they combine deep expertise in space-qualified semiconductor devices with the rigorous testing and certification heritage of a major industrial inspection body. Few organizations bridge the gap between advanced photon detection R&D (avalanche photodiodes, SPADs, VCSELs) and the qualification standards required for space deployment. Their move into cybersecurity certification for critical infrastructure suggests they are applying this quality-assurance DNA to new domains.
