Directional coupling between dielectric and long-range plasmon waveguides

Journal Article

We have designed, fabricated and characterized integrated directional couplers capable of converting the mode of an optical dielectric waveguide into a long-range plasmon propagating along a thin metal stripe. We demonstrate that the coupling between the two types of waveguides is generally very weak unless specific conditions are met. This sensitivity could be potentially exploited in sensing applications or for developing novel active photonic components. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
