Query: Phase sensitive detection of dipole radiation in a fiber-based high
  numerical aperture optical system   We theoretically study the problem of detecting dipole radiation in an
optical system of high numerical aperture in which the detector is sensitive to
\textit{field amplitude}. In particular, we model the phase sensitive detector
as a single-mode cylindrical optical fiber. We find that the maximum in
collection efficiency of the dipole radiation does not coincide with the
optimum resolution for the light gathering instrument. The calculated results
are important for analyzing fiber-based confocal microscope performance in
fluorescence and spectroscopic studies of single molecules and/or quantum dots.
