### Abstract

Single-mode optical fibers provide the ideal receiver optics for dynamic light-scattering measurements. Theoretical analysis shows that with a single-mode fiber one can achieve a theoretical limit of 1 for the coherence factor while maintaining a high light-collection efficiency. In fact, the sensitivity of the single-mode receiver surpasses that of a classical two-pinhole setup with a coherence factor of 0.8 by a factor of 4 and the advantage increases rapidly when a still higher coherence factor is desired. In addition, a single-mode fiber receiver offers the possibility of working with an arbitrary large scattering volume and with an arbitrary working distance. All these features are also demonstrated experimentally by a remarkably simple apparatus that consists, essentially, of a commercial laser beam delivery assembly.

- It cannot be emphasized strongly enough that the transverse coherence of the guided field is not just a consequence of the tiny entrance aperture of the fiber that would select an area much smaller than a speckle from the interference pattern. A perfect selection of a single mode requires an optical cavity such as is formed by the refractive-index profile of a long fiber.

- The relation of this equation to the continuum picture of the suspension becomes evident when one recalls the definition of the instantaneous number density of the particles: cn(r, t) = ΣiNδ[r − ri(t)].
- For another example of a single-mode receiver, a short dipole antenna, the visualization is more difficult. Unlike the launched electromagnetic field E−, H− of a dipole, which is the well-known Hertz field, the receiver field E+, H+ does not represent any physically realized solution of Maxwell equations. It is, in fact, the advanced solution.

- Note that the integral ¼∫[j*(r, t) · E+ (r)]d3r does have the unit of energy per time. This suggests its relation with the interaction Hamiltonian of the quantum theory of light. In fact, the projection amplitude P(t) is closely related to the transition amplitude for the transfer of photons from the source j into the state characterized by E+, H+. These topics, however, are beyond the scope of this paper.

- Recall that we have equipped the receiver with a polarizer in order to have a true single-mode case. Otherwise we would have to take into account the fact that the monomode fiber guides two orthogonal polarization modes equally well. Equation (7) would then consist of two terms differing only in the polarization of the receiver modes E+1 and E+2. One of the polarization directions can be freely chosen to be parallel with the polarization of the illuminating beam.
