Title: Enhanced coupling between light and surface plasmons by nanostructured Fabry-Pérot resonator
Published: September 26, 2011
Abstract: It is recognized that surface plasmons (SPs),which can be present on particulate, smooth, or corrugated metallic surfaces, have enormous potential in the fields of novel nano-optical and opto-electronic devices, as well as in spectroscopic, biological, and medical applications. For example SP integration into optical interconnects could support increased data transmission rates of more than a thousand times that of current electronic interconnects. These emerging applications are the result of the unique properties of SPs, which are confined to surfaces and can be focused laterally to dimensions substantially smaller than the light wavelength at comparable frequencies. Successful integration of nano-plasmonics with silicon technology radically depends on the conversion efficiency of modulated free space light into SP modes. In this letter we demonstrate a significant enhancement in the efficiency of free space light conversion into SP modes by a Fano resonance in a designed and fabricated nano-structured Fabry-Pérot (FP) resonator coupler.
