Abstract
Coupling of light to subwavelength structures and its control pose one of the greatest challenges of recent research [1]. Modification of spontaneous emission of an atom by a nanofiber has been studied in the context of two-level atoms [2]. The knowledge of both diagonal and off-diagonal types of decay characteristics is required for the studies of absorption and emission properties, optical response, and dynamical behavior of atoms. The knowledge of spontaneous emission characteristics is important yet from the angle of atom optics, in particular, from design considerations of atom traps. A recent proposal for trapping of individual atoms involves the use of a nanofiber with a single (red-detuned) [3] or two (red- and blue-detuned) light beams [4] launched into it.
