Current research in guided optics aims to create systems that are easily reconfigurable (“smart systems”), more compact, and less energy-intensive. This makes it possible to target new applications in the fields of telecoms and sensors, for example related to chemical species analysis or embedded/distributed systems. It is all the more crucial to develop this type of optical systems as they are essential for the practical and large-scale deployment of new technologies (e.g. connected objects, social networks, chemical species analyses, etc...) that are very demanding in terms of access points to the global network and data flows to exchange. In this context, the Optiflex project, led by the Interdisciplinary laboratory Carnot de Bourgogne, proposes several technological advances based on all-optical solutions for signal processing and chemical pollutant analysis. Specifically, we will develop solutions for the storage and sharing of optical data in the core network through the design of optical buffers coupled with a new time compression technique. We will also develop an optical chip continuum spectroscopy system for the detection and analysis of chemical species and study a new supercontinua production strategy based on the excitation of an out-of-equilibrium electronic population within a nanometric antenna.
