Abstract
We have derived analytical expressions for the angular distribution P(α) of the power radiated by magnetic or electric dipoles located at distance z0 from a dielectric interface and oriented perpendicular to it. For dipoles in the rarer medium very close to the interface, evanescent waves in the dipoles’ near field give rise to strong radiation into the denser medium. The resulting large maximum of P(α) shows characteristic differences for magnetic and electric dipoles when the relative refractive index of the two dielectrics is greater than √2. For dipoles lying on the interface a symmetry relation is established connecting the power distributions P(α) for the values n and 1/n of the relative refractive index.

Single molecules observed by near-field scanning optical microscopy.

TL;DR: Individual carbocyanine dye molecules in a sub-monolayer spread have been imaged with near-field scanning optical microscopy and the orientation of each molecular dipole can be determined to map the electric field distribution in the near- field aperture with molecular spatial resolution.

Absorption and Emission of Evanescent Photons

TL;DR: In this paper, it is confirmed that absorption proceeds at a rate proportional to the second-order product of the complex field amplitude, whether the light field is homogeneous or evanescent, and that the emission process follows a reciprocity principle.

TL;DR: In this paper, the fluorescence lifetime of an excited molecule described as a classical oscillating dipole in front of a partially reflecting plane interface is studied theoretically, the lifetime being inversely proportional to the radiated power.
