TLDR
In this paper, a relation between the normalized radiated powers radiated by magnetic and electric dipoles is established, and the authors show that the classical results for the radiated power yield the correct normalized spontaneous emission rates from an excited atomic state for electric and magnetic dipole transitions, respectively.Abstract:
Expressions for the total power radiated by magnetic and electric dipoles of arbitrary orientation located in a medium 1 at distance z0 from the interface to a homogeneous or planar stratified medium 2 are derived. A relation between the normalized powers radiated by magnetic and electric dipoles is established. For a homogeneous loss-free medium 2, curves of the normalized powers L(z0)/L∞ radiated by magnetic and electric dipoles versus the normalized distance z0/λ1 are presented for different values of the relative refractive index n = n2/n1 as the only parameter. The computer calculations are compared with analytical expressions derived for small and large distances. For n > 1, the contribution of the evanescent waves to the radiated power is calculated separately. We show that the classical results for the normalized radiated power yield the correct normalized spontaneous emission rates from an excited atomic state for electric and magnetic dipole transitions, respectively. We point out that the results for the electric dipole also give the change of the total power scattered by a small dielectric scattering particle when it is placed close to an interface.read more

Single-photon sources
Brahim Lounis,Michel Orrit +1 more
TL;DR: In this article, the authors discuss potential applications of single-photon states to optical processing of quantum information: cryptography, computing and communication, and compare the advantages and weaknesses of various single nanometre-scale objects used as singlephoton sources: atoms or ions in the gas phase and, in condensed matter, organic molecules, defect centres, semiconductor nanocrystals and heterostructures.

Influence of a dielectric interface on fluorescence decay time
TL;DR: In this article, the decay time of fluorescence molecules placed directly at the interface between a medium of refractive index 1.54 and air was investigated, and it was shown that fluorescence decay time varies markedly due to the presence of a reflecting interface between two dielectrics of different refractive indices.
