SILIOS TECHNOLOGIES SA

Their core work

SILIOS TECHNOLOGIES is a French SME that designs and manufactures optical spectral filters and multispectral imaging components — the hardware layer that enables cameras and sensors to see beyond the visible spectrum. Their technology underpins image sensing systems that capture data across multiple wavelength bands simultaneously, which is essential for applications where standard cameras fail. In H2020, they contributed this spectral filtering capability to two distinct domains: an advanced image sensing platform under the ECSEL Electronic Components programme, and a medical photoacoustic imaging system for cardiovascular risk assessment. Their value to a consortium is a proven, manufacturable optical component that bridges precision optics and real-world sensing applications.

What they specialise in

How they've shifted over time

SILIOS entered H2020 through EXIST, a broad electronic image sensing programme under the ECSEL scheme — a foundational positioning as a photonics component supplier for the European semiconductor and imaging industry. Their second project, CVENT, shifted into a specific high-value application: multispectral photoacoustic imaging for cardiovascular diagnostics. This move from horizontal technology platform to targeted medical application suggests a deliberate strategy of using their optical filter IP to enter regulated, higher-margin verticals. The trajectory in their short H2020 record runs from "we make imaging components" toward "our components solve specific clinical problems."

SILIOS is moving from general-purpose optical components toward specialized medical and diagnostic imaging instruments, where their spectral filtering IP commands higher margins and deeper integration into end-product workflows.

How they like to work

SILIOS has participated exclusively as a consortium partner, never as coordinator — the typical posture of a specialized component supplier that joins larger projects to provide enabling hardware rather than to lead system integration. Their 28 unique partners from just 2 projects indicates involvement in large, multi-actor consortia (consistent with ECSEL-RIA structures). This profile suggests they are a reliable technology contributor that brings a specific, hard-to-replace optical component rather than broad project management capability.

SILIOS has connected with 28 unique consortium partners across 6 countries through only 2 projects, reflecting the large consortium structures typical of ECSEL-RIA and health-focused RIA calls. Their network is European in scope with no visible geographic concentration beyond France.

What sets them apart

SILIOS occupies a rare position as a small French manufacturer of multispectral optical filters that has demonstrated credibility in both the European electronic components ecosystem (ECSEL) and biomedical photoacoustic imaging research — two domains that rarely share the same industrial partner. For a consortium needing a proven spectral filter supplier that understands both ICT integration requirements and medical device constraints, SILIOS removes a key supply-chain risk. Very few SMEs of this size can point to validated contributions in both semiconductor-grade image sensing and clinical cardiovascular imaging within the same decade.

Highlights from their portfolio

• CVENT
  Largest single grant (EUR 265,656) and the most cross-sector project in their portfolio — applying multispectral photoacoustic imaging to cardiovascular risk assessment, which bridges precision optics directly into clinical medicine.
• EXIST
  Funded under ECSEL-RIA, the European programme for electronic components and systems, validating SILIOS as a recognised photonics supplier within the EU's strategic semiconductor and imaging supply chain.
