Query: Spectroscopy, Manipulation and Trapping of Neutral Atoms, Molecules, and
  Other Particles using Optical Nanofibers: A Review   The use of tapered optical fibers, i.e., optical nanofibers, for spectroscopy
and the detection of small numbers of particles, such as neutral atoms or
molecules, has been gaining ground in recent years. In this review, we briefly
introduce the optical nanofiber, its fabrication and optical mode propagation
within. We discuss recent progress on the integration of optical nanofibers
into laser-cooled atom and vapor systems, paying particular attention to
spectroscopy, cold atom cloud characterization and optical trapping schemes.
Next, a natural extension on this work to molecules will be introduced.
Finally, we consider several alternatives to optical nanofibers that display
some advantages for particular applications.
