Surface plasmon polariton scanning quantum source

A crucial obstacle to the further miniaturization of electrical devices is the difficulty of making electrical contacts between nano-objects. Indeed, energy transfer and communication between devices at the nanometer scale has become a major issue in developing nano-electronic or nano-optical devices. Recently, photonic and plasmonic methods have been proposed to address these problems. Surface Plasmon Polaritons (SPPs), which are hybrid state electronphoton modes propagating at the interface between a metal like gold and an insulator (e.g., glass or air), are naturally adapted for two-dimensional applications. As surface waves, SPPs are exponentially damped in the directions perpendicular to the interfaces and can be guided in structures that are miniaturized beyond the di" raction limit. These appealing properties make (Full text)
