Critical coupling in plasmonic chain for efficient energy trapping
Plasmonic nanoparticles can concentrate electromagnetic energy on the nanometer scale, offering promising applications in diverse fields such as miniaturized photonic circuits or lab-on-chip. An essential prerequisite for these applications is efficient coupling between the nanoparticles and the excitation signal. Plasmonic nanoparticle chains are capable of guiding light on a sub-wavelength scale, and can be excited by being coupled to a dielectric waveguide. Here, a team from C2N proposes a …
Solar photovoltaics in France (3rd edition) : reality, potential, and challenges
What is the current state of solar photovoltaic development in France ? What role could it play in the country’s future energy mix? This third edition of the Photovoltaic Solar Guide — enriched with numerous fact sheets and prepared by a group of researchers from C2N, the Ile-de-France Photovoltaic Institute (IPVF), and the French Photovoltaic Research Federation — aims to support informed public discussion on the energy transition in France. …
