The confinement and the enhancement of light into the nanometer scale represent an advance in the development of efficient and compact optical sources and sensors, useful in quantum information and biomedical applications. However, the optical confinement of light to the nanometer scale cannot be reach with optical components fabricated with dielectric materials because of the diffraction limit. The use surface plasmons-polaritons supported by metallic nanostructures overcomes this limit and therefore, confines the light to the subwavelength scale. In this contribution, recently published in Nano Letters, we demonstrated the confinement and the enhancement of light in integrated plasmonic structures on silicon photonics. With the use of near field scanning optical microscopy, we reveled the extreme confinement of light. This phenomenon opens novel routes for the development of quantum information, telecommunications, and biomedical applications.
