Giant Coupling Effect between Metal Nanoparticle Chain and Optical Waveguide

Résumé

We demonstrate that the optical energy carried by a TE dielectric waveguide mode can be totally transferred into a transverse plasmon mode of a coupled metal nanoparticle chain. Experiments are performed at 1.5 μm. Mode coupling occurs through the evanescent field of the dielectric waveguide mode. Giant coupling effects are evidenced from record coupling lengths as short as 560 nm. This result opens the way to nanometer scale devices based on localized plasmons in photonic integrated circuits.
