LEO SPACE PHOTONICS R&D MONOPROSOPIIKE

Their core work

Leo Space Photonics R&D is a Greek SME specializing in photonic technologies for satellite communications. They develop optical communication systems — including laser modems, optical transceivers, and photonic payloads — designed to replace or augment traditional radio-frequency links on satellites. Their work targets both inter-satellite and satellite-to-ground optical links, addressing the growing demand for very high throughput satellite (VHTS) architectures. They bridge the gap between silicon photonics research and space-grade hardware, focusing on components like semiconductor optical amplifiers, modulators, and photo-detectors for on-board satellite use.

What they specialise in

How they've shifted over time

Leo Space Photonics started with a focus on point-to-point laser communication between satellites (ORIONAS, 2018), concentrating on the fundamental building blocks: silicon photonics chips and semiconductor optical amplifiers for a laser communication modem. By 2020, their scope had broadened significantly — SIPhoDiAS moved into full photonic payload systems including digital processing, microwave-photonic conversion, and a wider range of opto-electronic components. The trajectory shows a clear shift from discrete optical link components toward integrated, multi-function photonic systems for next-generation satellite architectures.

They are moving from building individual optical link components toward designing complete photonic payload systems for very high throughput satellites — positioning themselves for the growing commercial satellite constellation market.

How they like to work

Leo Space Photonics frequently leads projects, coordinating 2 out of 3 H2020 efforts, which is unusual for an SME of this size and suggests strong technical leadership and proposal-writing capability. With 16 unique partners across 7 countries from just 3 projects, they work in mid-sized consortia with a broad European network rather than relying on a fixed set of repeat partners. For potential collaborators, this means they are comfortable taking the lead on technically ambitious proposals and managing international teams.

They have built a network of 16 partners across 7 countries through just 3 projects, indicating diverse European connections in the space photonics community. Their base near Athens (Agia Paraskevi, home to Greece's National Observatory) places them in a space-tech cluster.

What sets them apart

Leo Space Photonics occupies a niche at the intersection of photonics and space communications — a domain where few European SMEs operate as project coordinators rather than subcontractors. Their progression from component-level work to full payload integration suggests they are building end-to-end system capability, making them a valuable partner for satellite primes and constellation operators who need photonic expertise without going to large aerospace contractors. For a small Greek company to twice win coordination of EU space research projects signals strong credibility in a competitive field.

Highlights from their portfolio

• SIPhoDiAS
  Their largest project (EUR 443K) and most ambitious scope — space-grade photonic interfaces for both digital and analogue satellite payloads, coordinated by this SME.
• ORIONAS
  Their first coordinated project, tackling lasercom-on-chip for satellite constellations — a foundational effort that set their technical direction.
