Séminaire ICE « Which perspectives for silicon photonics ? »
Silicon is the mainstream material in the electronic industry and it is rapidly expanding its dominance into the field of photonics. Indeed, silicon photonics has been the subject of intense research activities as a compelling technology paving the way for next generation of energy-efficient high-speed computing, information processing and communication systems. The trend is to use optics in intimate proximity to the electronic circuit, which implies a high level of optoelectronic integration. Over the last decade, the field of silicon photonics has advanced at a remarkable place. Most applicative sectors have now included silicon photonics in their roadmaps as a key technology to be deployed over short, medium or long-term horizons. This evolution towards silicon-based technologies is largely based on the vision that silicon provides a mature integration platform supported by the enormous eisting CMOS manufacturing infrastructure which can be used to cost-effective produce integrated optoelectronic circuits for a wide range of applications, including on-chip communications, sensing, microwave photonics, optical spectroscopy, quantum technology. Recent advances and new trends in the development of silicon photonics devices will be presented and discussed.
Dr Vivien is a CNRS researcher at the Center for Nanoscience and Nanotechnology, a joint Laboratory of CNRS and University of Paris Saclay, France. His research activities focus on the development of fundamental concepts and devices in the silicon photonics platform including optoelectronic devices (detectors and modulators) and hybrid photonic integration (carbon nanotubes, chalcogenides, crystalline oxides,…). Since 2016, he has served as Deputy Director of C2N and Director of the Photonics Department. In 2015, he received the Consolidator European Research Council (ERC) grant on the development of strained silicon photonics. He is an elected Fellow of OSA, EOS and SPIE. He regularly serves as a Chair or a program committee member of SPIE, EOS, OSA and IEEE conferences on photonics and optoelectronics.
