Microwaves and OPtics: from Electromagnetism to Systems

The HOPES department exploits optical and microwave approaches to meet the challenges posed by the future Internet of Things and machine-to-machine communication. The overall aim is to advance the state-of-the-art in electronic and photonic components, which will have a major impact on the development of cyber-physical and intelligent systems. Research aims to advance knowledge and propose innovative solutions for embedded and autonomous systems, enabling interconnected objects to communicate and interact with their environment. More generally, this broadly interdisciplinary field of research paves the way for new-generation technologies, through the joint exploitation of chemical or biological principles, notably for the environment, health and biological systems. Our activities cover a wide range of materials, components and systems, for applications in which electromagnetic energy plays a key role: communications networks, embedded systems, sensors, imaging, biology, etc. Our work covers the essential building blocks of optical and electrical engineering, from an in-depth understanding of physical phenomena and material properties, to the development of new modeling concepts and techniques, manufacturing technologies, test and measurement methodologies, leading to validation of prototypes

Olivier Gauthier-Lafaye

The HOPES scientific department draws on the expertise of four teams exploring complementary aspects of electronics and photonics to propose basic functionalities that meet the requirements of miniaturization, multifunctionality and low power consumption, and are suitable for integration within interconnected components or intelligent systems. Research in this field is benefiting from the growing convergence between the fields of optics and electronics, and their mutual enrichment through shared applications. In addition, the rise of nanotechnologies offers new opportunities to establish a unified vision of systems integration, based on the implementation of generic technologies enabling the heterogeneous integration of electronic and photonic devices in intelligent systems. HOPES develops advanced manufacturing processes at the cutting edge of nanotechnology, and takes a specifically interdisciplinary approach by linking these technological activities to the exploration of alternative component concepts that meet society's needs.
