Company Profile:
The Photonics Engineering Group (GRIFO) of the Electronic department at the University of Alcalá de Henares holds ample experience at developing research projects in Applied Photonics. In the last 5 years it has taken part in over 15 projects and research contracts both public and private, national and european, in this field. The span of the projects covers foundation topics (like the first proof of slow light in optic fiber, generation of supercontinuum in optic fiber, and the study of nitrides for photonic devices), and applied research (like semiconductor devices development, fiber optic sensors...). Some of the outcomes of these projects have sucessfully been transferred and are currently being exploited by european companies.

Temperature and strain fully distributed fiber optic sensor.

What we offer:
The Photonics Engineering Group (University of Alcalá de Henares) offers a 2 meter resolution long-range Brillouin distributed temperature and strain fiber optic sensor that reaches 100 km. The sensor is low cost, flexible and integrable in all kinds of civil infrastructure (tunnels, bridges, railways, etc).

Brillouin distributed optical fiber sensors are one of the most useful systems to provide temperature and strain monitoring to large civil structures.

A distributed sensor provides measurements over its whole length as opposed to point sensors. As fiber optic behaves both as sensor and as carrier of the information its implementation is easy. Our sensor features accurate measurements over 100 km with as low as 2 meter resolution.

The sensor is based on the well established fiber optics technology which provides advantages such as low cost, small size, low weight and flexibility, ease of maintenance and integration. The sensor can be used in places where no electronics are allowed due to security or interference reasons. The sensor allows the monitoring of >10000 measuring points with a single fiber cable and a single interrogation unit.

What we are looking for:
The group seeks to collaborate with national and international research centers as well as companies to spread the range of possible applications of the system.

They are also interested in finding partners for R&D regional or nacional calls and european projects.

The group is looking for civil engineering companies or aeronautic that need to control the strain in their systems or structures (pipes, bridges, aircrafts). Environment related companies interested in temperature and strain measurement. And companies interested in temperature and strain control integrated with alarm sensors.

Distributed fibre-optic Intrusion sensor

What we offer:
We offer a distributed optical fiber sensor for vibration monitoring. The sensor is based on optical reflectometry and provides 4 meter resolution and 40 km range. The system is able to detect vibrations ranging from human footsteps up to heavy vehicles passing.

The set-up can be used to generate a secure perimeter by monitoring the vibrations present. Thus, any deviation from the usual pattern can be detected. This can be applied to different security related situations like intrusion detection, natural risks surveillance, transport tracking and civil infrastructures supervision among others.

What we are looking for:
The group seeks to collaborate with national and international research centres as well as companies to spread the range of posible applications of the system.

They are also interested in finding partners for R&D regional or national calls and european projects.
