MULTITEL is a Belgian private, non-profit research centre, leading applied research and development activities for industry leaders, SMEs and spin-off companies. It was initiated by the “Faculté Polytechnique de Mons” and “Université Catholique de Louvain” under initiatives supported by the European Commission and the Walloon Region. Multitel is active in five interrelated R&D areas: photonics, signal processing and data fusion, image processing and coding, speech technologies and local networks. Multitel is a technology transfer medium. Many spin-off companies have already emerged from the centre: BABEL Technologies (now ACAPELA Group), IT-OPTICS, SMARTWEAR, ACIC, POLYMEDIS. Multitel has an international reputation with the industrial services offered in the field of the optical metrology (field characterisation of optical networks, reliability of optical sub-systems and components, periodical calibration of optical tests equipment, etc.). Multitel also participated in various European projects, mainly focused on measurement technologies, reliability, as well as on optical fibre sensors and lasers. One of the most relevant project is the FP6 IP NextgenPCF. In this project Multitel developed high power pulsed and CW fibre lasers seed sources for supercontinuum generation and Raman lasers. Furthermore, in NextgenPCF Multitel has also worked on splicing and handling issues related with PCF fibres. For NextgenPCF as well as for ALPINE, Multitel will use its experience and up-to-date photonic equipment (optical spectrum analyzers, arc and filament fusion splicer, high power meters, high speed detectors as well as a class 100 000 clean room) to develop highly reliable and performing lasers in ad equation with the requirements of the project. Multitel is ISO certified and can deliver both in time and with industrial quality and takes part in several European projects.
Role in the project
Multitel contributes to the laser design, for instance bringing the expertise in design and prototyping of high-power short pulse sources.
The key personnel to be involved in the project activity includes:
Yves Hernandez: since 2003, Dr. Hernandez is group leader with the Applied Photonics Department of Multitel. He is coordinating the R&D activities on fibre laser sources. Dr. Hernandez is co-author of about 20 scientific publications on semiconductors and laser technology. Yves Hernandez received the Ph.D. Degree in Optoelectronics with IEMN and University of Lille in 2001. His doctoral thesis concerned the fabrication of optical switches on InP-based technology and was carried out in collaboration with French DGA (Direction Générale de l’Armement) and THALES Airborne Systems. From 2001 to 2003 he was responsible for product development, regarding the Reliability of Semiconductor Laser Diodes, with Alcatel Optronics (France).. His domains of expertise are: materials, semi-conductors and thin film technology, optical propagation on planar technology, characterization of optical devices, knowledge of failure mechanisms of photonic components and fibres lasers and amplifiers design.
Anthony BERTRAND graduated “Optoelectronic engineer” from ENSSAT (Ecole Nationale Supérieure des Sciences Appliqués et de Technologie, Lannion, France) joined the Applied Photonics Department of Multitel in October 2007. He previously worked with PERFOS (Plate forme d’Etude et de Recherche sur les Fibres optiques Spéciales, Lannion, France) on characterisation of PCF fibres and CEA (Commissariat à l’Energie Atomique, Bordeaux, France) on the Laser Méga Joule Project. For MULTITEL he was strongly involved in the FP6 project NextgenPCF, carrying on the fibre laser development and prototyping of Ytterbium pulsed fibre lasers sources.
