I.D.I.L. SAS (INGENIERIE-DEVELOPPEMENT-INSTRUMENTATION-LASER)

Their core work

IDIL SAS is a French laser instrumentation SME based in Lannion — France's photonics hub — that designs and develops fiber optic sensing systems based on laser reflectometry. Their core technology is BOTDR (Brillouin Optical Time Domain Reflectometry), a laser-based method that measures distributed strain and deformation along the full length of a fiber optic cable. In practice, this means they can turn kilometers of optical fiber into a continuous sensing array — detecting ground movement, fault slip, or seafloor deformation at spatial resolution impossible with point sensors. Research consortia bring them in to provide the optical interrogator hardware and measurement expertise that makes distributed fiber sensing experiments possible in the field.

What they specialise in

How they've shifted over time

IDIL entered H2020 through the CO2 storage domain — applying their fiber sensing technology to monitor underground storage integrity and detect ground deformation at onshore pilot sites. Their more substantial and longer-running project, FOCUS (an ERC Advanced Grant running to 2025), marks a clear pivot toward marine geohazards: earthquake fault monitoring, seafloor deformation, and distributed sensing in the Mediterranean basin. The shift from CO2 storage to seismic hazard monitoring reflects both a broadening of application domain and a move toward higher-precision, larger-scale deployments where BOTDR and distributed sensing have the greatest advantage over conventional instruments.

IDIL is positioning itself as a specialist supplier of distributed fiber optic sensing hardware for large-scale geophysical observation networks — a niche that is growing fast as subsea cable infrastructure expands and earthquake early-warning systems demand higher spatial resolution.

How they like to work

IDIL participates exclusively as a consortium partner — they have never led an H2020 project — which is consistent with the role of a specialist instrument provider that joins consortia to supply hardware and measurement expertise rather than scientific leadership. Their two projects involved large consortia (32 unique partners across 17 countries), suggesting they are comfortable operating as a focused technical contributor within complex, multi-institutional teams. Working with them likely means procuring or co-developing a specific sensing instrument or measurement protocol, not managing a broad research collaboration.

Despite only two projects, IDIL has built an unusually wide network — 32 unique partners across 17 countries — driven by the large, international consortia typical of ERC and RIA instruments. Their geographic footprint is pan-European, with a notable Mediterranean dimension through FOCUS.

What sets them apart

IDIL occupies a narrow but high-value niche: they are one of very few SMEs in France that combine laser engineering capability with field-deployable distributed fiber optic sensing for subsurface and seafloor geophysical applications. Unlike academic photonics labs, they are an engineering company — they build instruments that work in the field, not just in the lab. For a consortium needing BOTDR interrogators or distributed sensing expertise alongside geological or environmental scientists, IDIL provides the technology bridge that most research groups cannot build internally.

Highlights from their portfolio

• FOCUS
  An ERC Advanced Grant (2018–2025, EUR 545,625 to IDIL) deploying fiber optic cables on the Mediterranean seafloor to monitor active earthquake faults — one of the most technically ambitious applications of distributed sensing in EU research.
• ENOS
  Pan-European CO2 storage pilot consortium (2016–2020) where IDIL contributed monitoring instrumentation across onshore field experiments, demonstrating cross-sector application of their sensing technology.
