Photonic Engineering Research Group

The activity of the GRIFO (Photonic Engineering Research Group) of the University of Alcala is very intense in terms of scientific production. In particular, we work in the research line of distributed fiber optic sensors, in the field of development and manufacture of photonic materials and devices based mainly on group III nitrides, and in the application of ferroelectric/piezoelectric materials with perovskite structure with different compositions for energy harvesting systems.

  • Distributed Fiber Sensors.

    In the last five years, the activity in The Photonics Engineering Research Group GRIFO has been very intense in terms of scientific production. In particular, in the research line of distributed fiber optic sensors 2016 was a particularly important year as a new technique for distributed acoustic sensing (DAS) was demonstrated by the group. Since then, this technique has been at the core of many investigations of this group in the last five years, as it offers disruptive properties that have not only spurred the interest of the scientific community, but also from commercial companies which license the patents associated to the technique and have developed it into commercial products (particularly Omnisens, CH, and Aragon Photonics, ES).

  • Fabrication of materials and photonics devices.

    The group has been involved in the field of development and fabrication of materials and photonics devices based mainly on group III nitrides. Within these research lines, the group has a deep expertise in the deposition of metals and III-Nitrides by sputtering on several kind of surfaces, like standard optical fibre, flexible substrates, sapphire and Silicon.

  • Ferroelectric/piezoelectric materials with perovskite structure for energy harvesting systems.

    Integration, characterization, modelling (FEM) and application to electronics of ferroelectric/piezoelectric materials with perovskite structure with different compositions. That line has evolved in the combination of these piezoelectric materials with magnetic materials to manufacture multiferroic materials (in a single phase and composites) for energy harvesting systems.
