22 Feb 1977
TL;DR: In this paper, the polarization sensitivity of single-mode optical fibers has been investigated and an additional implication of the sensitivity is the introduction of delay distortion in'single' mode fibers.
Abstract: The polarization characteristics of 'single' mode optical fibers have been the subject of several publications . An understanding of the polarization sensitivity of such fibers is important in assessing the applicability of polarization dependent optical circuitry . An additional implication of the polarization sensitivity is the introduction of delay distortion in 'single' mode fibers.

TL;DR: In this paper, a broad class of practical, multimode, circular-symmetric, isotropic, optical fibers having any numerical aperture and any profile dispersion (which is a function of the derivative of the index with respect to the wavelength) was studied.
Abstract: Design criteria to minimize modal dispersion have been found for a broad class of practical, multimode, circular-symmetric, isotropic, optical fibers having any numerical aperture and any profile dispersion (which is a function of the derivative of the index with respect to the wavelength). The impulse-response width of these fibers, the rms width of the impulse response, the optimum profiles to minimize those widths, and the sensitivity to profile departures from ideal are found to be surprisingly simple closed-form generalizations of previous results that are mostly applicable to fibers with small numerical aperture and constant profile dispersion. The minimum impulse-response width of the optimized fiber is a function only of its numerical aperture and consequently is independent of the index profile and of the profile dispersion.

TL;DR: In this article, the authors evaluated the dispersion in a single-mode fiber by measuring propagation times of various-wavelength pulses transmitted through a 3.72 km-length fiber.
Abstract: Wavelength dispersion in a single-mode fibre has been evaluated by measuring propagation times of various-wavelength pulses transmitted through a 3.72 km-length fibre. Dispersion in a single-mode fibre is dominated by material dispersion, and is estimated to be 9.1 ps/A dkm at 0.85 μ m wavelength.
