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 …
