THALES is a world leader group for electronics and a key player in numerous markets such as aerospace, space, ground transportation, digital identity and security, physical and cyber security and defense. Completed in 15 months, the acquisition of Gemalto by Thales for €4.8 billion creates a Group on a new scale and a global leader in digital identity and security employing 80,000 people in 68 different countries. The larger Thales will master all the technologies underpinning the critical decision chain for companies, organizations and governments, and will develop secure solutions to address the major challenges faced by our societies, such as unmanned air traffic management, data and network cybersecurity, airport security or financial transaction security. Research and development (R&D) is at the core of the new Group, with its 3,000 researchers and 28,000 engineers dedicated to R&D. Thales has been developing state-of-the-art technologies to meet the most demanding requirements of customers around the world for decades. Today the Group has become a giant laboratory inventing the world of tomorrow, with a portfolio of 20,500 patents, of which more than 400 new ones were registered in 2018. THALES participates to the k-NET project with Thales Research & Technology France (TRT-fr), the main multidisciplinary research unit of THALES, located on the Campus of Polytechnique in Palaiseau. Through its internal activities and scientific links with industries and universities, either in France or internationally, TRT is participating in the preparation of THALES industrial future in strategic R&D fields. In addition to R&D activities, TRT-fr also provides scientific and technical advice, expertise or services for the company. TRT-fr accounts for 3% of total R&D of the Group and employs 220 full-time staff and over 40 PhD students. The center has more than 13000 m2 of labs and 1700 m2 of clean rooms. TRT-fr has a strong record track in optics & optoelectronics, electronic components for microwave applications, III-V components, optical & biochemical detection devices, lasers, packaging, materials, software architecture and cognitive science. TRT-fr research teams have very diverse skills ranging from materials elaboration (polymers, epitaxy of various semiconductors, superconductors, dielectric or magnetic thin films, ceramics, etc.), through component modelling, processing, testing, assembly and packaging, to integration in appropriate demonstrators, which allow full validation of the technologies investigated before their transfer to operational divisions of Thales Group.
