Abstract
Optical near fields exist close to any illuminated object. They account for interesting effects such as enhanced pinhole transmission1 or enhanced Raman scattering enabling single-molecule spectroscopy2. Also, they enable high-resolution (below 10 nm) optical microscopy3,4,5,6. The plasmon-enhanced near-field coupling between metallic nanostructures7,8,9 opens new ways of designing optical properties10,11,12 and of controlling light on the nanometre scale13,14. Here we study the strong enhancement of optical near-field coupling in the infrared by lattice vibrations (phonons) of polar dielectrics. We combine infrared spectroscopy with a near-field microscope that...
