Vicente Durán, researcher from the Optics Research Group (GROC) at the Universitat Jaume I (UJI) in Castelló and member of the Department of Physics at this very University, will develop a research project for a two-year period at Chalmers University of Technology in Gothenburg (Sweden) thanks to financing from Marie Sklodowska-Curie Actions-Research Fellowship Programme, within the EU Horizon 2020 Programme. The research project in which Durán will be involved, that is midway between physics and engineering, aims to design and develop a light radar (LIDAR) capable of measuring distance with superior accuracy at high speeds (millions of times per second).

The development of this kind of radars is possible by using special light sources named “frequency combs” that were already used for building extremely accurate optical clocks, discovered by Theodor W. Hänsch and John L. Hall, who shared the Nobel Prize for Physics in 2005. The introduction of these accurate optical tools provides to traditional LIDAR systems some benefits that have never been reached until now, regarding speed and resolution; they also cover a wide range of distance (between a few millimetres and a kilometre). There is a broad range of applications for these systems, from vibrometers and speedometers design to detection of particles moving in a fluid at high speed.

Marie Curie Actions are involved in the Excellent Science programme, which is one of the pillars of the EU Horizon 2020 Programme. This programme aims to enhance the researchers’ professional career, as well as promoting their mobility. Especially, actions within Europe allow experienced researchers to move within Europe to work with an expert from another country on a scientific topic that is new for them. Applicants develop a project in collaboration with the host university, where the objectives intended to be attained with this fellowship, both in the scientific and the professional field, are specified. The criteria followed in selecting the winners are entirely scientific and the assessment is done by European independent experts.

The underlying aim of this project is to facilitate a normal collaboration between researchers from the GROC Group at the UJI and the optical fiber research group led by the professor Peter Andrekson at the Departement of Microtechnology and Nanoscience in Chalmers University, where Vicente Durán is staying.

The professor Andrekson, who developed his postdoctoral activity at the prestigious laboratory Bell in the early 1990s, has received numerous awards in his country and has been expert, two times, for the election of the Nobel Prize for Physics.
